Duolingo is an app and website designed to help people learn languages in a simple and engaging way. It’s free to use, though there are paid options that remove ads and offer extra features. The lessons are short and interactive, with exercises that involve matching words, listening to sentences, speaking, and translating. A green owl named Duo acts as the app’s mascot—offering encouragement when you stay on track and reminders when you don’t. The platform offers a wide range of languages, from widely spoken ones like Spanish, French, and Chinese to less common choices like Welsh, Hawaiian, and even fictional languages like Klingon and High Valyrian. Lessons focus on practical, everyday communication—like ordering food or asking for directions—though you’ll occasionally encounter quirky sentences that are memorable in their oddness. Duolingo adapts to your progress: if you’re struggling, it slows down; if you’re doing well, it introduces more challenging material. There are game-like features—points, streaks, and levels—that keep learning motivating and fun. For those looking to go beyond basic lessons, Duolingo also offers podcasts, stories, and interactive exercises to improve listening and reading comprehension. Convenient and easy to use, Duolingo fits into almost any schedule—you can practice on the bus, during a lunch break, or before bed. While it’s not a complete substitute for full immersion or in-depth study, it’s a useful tool for beginners and a good way to keep language skills fresh.

This was my go-to page at the early stages of learning Mandarin. Chinese Grammar Wiki has an articles of each of the main aspects of Chinese grammar. For example, there are articles on how to use 一下, 在, 要, 就是, 才and many other Mandarin grammar points. Each word gets its own article with examples in pinyin and characters and, of course, English translations. You can also get website as a physical book or an ebook.

The Republic is a Socratic dialogue, written by Plato around 380 BC, concerning the definition of justice, the order and character of the just city-state and the just man—for this reason, ancient readers used the name On Justice as an alternative title (not to be confused with the spurious dialogue also titled On Justice). The dramatic date of the dialogue has been much debated and though it might have taken place some time during the Peloponnesian War, "there would be jarring anachronisms if any of the candidate specific dates between 432 and 404 were assigned". It is Plato's best-known work and has proven to be one of the most intellectually and historically influential works of philosophy and political theory. In it, Socrates along with various Athenians and foreigners discuss the meaning of justice and examine whether or not the just man is happier than the unjust man by considering a series of different cities coming into existence "in speech", culminating in a city called Kallipolis, which is ruled by philosopher-kings; and by examining the nature of existing regimes. The participants also discuss the theory of forms, the immortality of the soul, and the roles of the philosopher and of poetry in society.

"Nicomachean Ethics," written by the ancient Greek philosopher Aristotle, is a foundational text in Western philosophy. This work explores the nature of ethical virtue and the path to a good and fulfilling life. Aristotle delves into concepts such as happiness (eudaimonia), virtue (arete), and the importance of practical wisdom (phronesis). The text is a detailed examination of how individuals can achieve moral and intellectual virtues through habitual practice and rational deliberation.

"Fooled by Randomness" is a thought-provoking book by Nassim Nicholas Taleb that delves into the role of chance in our lives and how we often mistake random events for meaningful patterns. Through a mix of personal anecdotes, philosophical insights, and statistical analysis, Taleb explores how randomness affects the world of finance, business, and daily life. The book challenges readers to rethink their perceptions of success, failure, and the forces that drive outcomes. This book is ideal for readers interested in finance, probability, and the philosophical implications of randomness.

"The Bed of Procrustes" is a collection of aphorisms by Nassim Nicholas Taleb that distills his philosophical insights into short, thought-provoking statements. The title refers to the Greek myth of Procrustes, symbolizing the tendency to force things into unnatural conformity. Through these aphorisms, Taleb critiques modern society's flaws, biases, and misconceptions, offering a sharp, often humorous, commentary on topics ranging from knowledge and science to wealth and human behavior. This book is perfect for readers who enjoy deep, philosophical musings and appreciate Taleb's sharp wit and unconventional perspectives.

Drops is a language learning app that focuses on teaching vocabulary through quick, visual-based games. The idea is to make learning feel more like playing, with short sessions you can fit into your day. Instead of grammar-heavy lessons, it leans on matching words with pictures, swiping, and tapping to help words stick in your memory. The app covers over 40 languages, from common ones like Spanish and French to less common ones like Hawaiian and Ainu. You get common, everyday words and phrases to start with—things you’d actually use in conversation. It’s built for people who want to learn at their own pace, and there are features like reminders and streaks to keep you coming back. Drops keeps lessons short—usually five minutes—so it’s easy to squeeze in some learning while waiting for coffee or riding the train. There’s a free version with ads and limits on daily use, or you can pay for Premium to get rid of ads, unlock all content, and use it offline. Overall, it’s not going to teach you complex grammar or how to hold a full conversation right away, but if you’re looking to build your vocabulary in a fun, no-pressure way, it does the job.

Learning a new language is hard, you need a lot of repeated exposure to the same words to make them stick. Here's the trick I use. I open ThaiPod101's live channel and let it run in the background while I do something else. For example, I can have it open while cooking dinner or tidying up. Even if I look at the screen only occasionally, I still get the benefits of being repeatedly exposed to Thai vocabulary. This works particularly well in combination with other learning methods. If you have a smart TV or a Chromecast, you can even play it on your TV instead of regular TV channels. The channel runs 24/7 and replays ThaiPod101 lessons.

Italki is a platform connecting language teachers, mostly native speakers, with students. You can book, pay, and schedule your classes directly through their website. The classes are one on one, just you and the teacher, and conducted over a video call. I used Italki successfully before going to Thailand for the first time. My wife who is Thai gave me an Italki gift card. There are plenty of teachers to chose from and the rates are affordable. You'll pay anywhere from $10 to about $20 for a class.

A Gentleman in Moscow is a historical fiction novel by Amor Towles. It follows Count Alexander Rostov, a Russian aristocrat who, after the Bolshevik Revolution, is sentenced to house arrest in the grand Hotel Metropol in Moscow. Instead of being imprisoned in a cell, he’s confined to the hotel, which becomes both his cage and his world. The story spans several decades, starting in the 1920s and running through key moments of Soviet history. Most of it unfolds inside the hotel, which is no ordinary place—it's a bustling, self-contained universe. Rostov, who begins the story living in a lavish suite, is forced to move into a tiny attic room. Despite this fall from grace, he navigates his new life with wit and charm, forming friendships with the hotel staff, guests, and unexpected visitors. The book isn’t just about the Count’s personal journey—it’s also about how time changes people and places, how history creeps in even when you’re standing still, and how small acts of kindness and loyalty can shape a lifetime. The setting, the Metropol, is richly described, from fine dining rooms to back corridors. There’s a good bit about food, music, and Russian culture, and plenty of philosophical musings, but it never gets too heavy. At its core, the novel is about making the best of what life throws at you. The Count is an old-world gentleman stuck in a new world that wants to forget people like him. How he handles that—sometimes with grace, sometimes with stubbornness—is what makes the book compelling. It's quietly dramatic, occasionally funny, and surprisingly heartwarming, all without needing big action scenes.

Barbarian Days: A Surfing Life is William Finnegan’s story about growing up obsessed with surfing. It’s not just about catching waves—it’s about a whole way of life that’s demanding, addictive, and sometimes dangerous. Finnegan started young, learning to surf in California and Hawaii, and kept chasing waves into adulthood, traveling through places like Fiji, Australia, Indonesia, and Africa. Along the way, he mixes adventure with self-reflection, talking about friendships formed in the water, the culture around surfing, and how it all fit with the times—especially during the social changes of the 1960s and '70s. The book isn’t just about the thrill of surfing; Finnegan dives into the technical side of waves and the patience it takes to master them. He’s honest about his youthful recklessness—like taking LSD before surfing a massive wave in Maui—and the risks that came with his travels, from malaria scares to navigating shady markets. Still, surfing pulls him along, even when he’s juggling a career as a war reporter and later, family life. At its core, Barbarian Days is an old-fashioned adventure tale mixed with a thoughtful look at what it means to be hooked on something so completely. Finnegan’s writing captures both the beauty and the grind of surfing, making you feel like you’re right there with him—whether on a remote beach or paddling out into icy waves off Long Island.

Six days ago, astronaut Mark Watney became one of the first people to walk on Mars. Now, he’s sure he’ll be the first person to die there. After a dust storm nearly kills him and forces his crew to evacuate while thinking him dead, Mark finds himself stranded and completely alone with no way to even signal Earth that he’s alive—and even if he could get word out, his supplies would be gone long before a rescue could arrive. Chances are, though, he won’t have time to starve to death. The damaged machinery, unforgiving environment, or plain-old “human error” are much more likely to kill him first. But Mark isn’t ready to give up yet. Drawing on his ingenuity, his engineering skills—and a relentless, dogged refusal to quit—he steadfastly confronts one seemingly insurmountable obstacle after the next. Will his resourcefulness be enough to overcome the impossible odds against him?

Skin in the Game may be nice but The Black Swan is the OG Nicholas Taleb. Read this book to learn how to think and avoid biases and reread at least once very couple of years.

by George Orwell an expedition into who people are and what life is

The great thing about this book is that it takes a big-picture view of human history. It attempts to explain the main themes of human history without getting bogged down in the details. Sapiens also debunks many popular myths about human history, including the one that people today live happier lives and have better diets than our hunter-gatherer predecessors. It comes with an epilogue about the future of humankind in light of ever-accelerating technological progress. With the recent advances in AI it is more relevant than ever. If you're going to read one book on history this year, read this one.
