Learn how to learn in six weeks
Six weeks — about 30 hours — replaces the study habits you picked up at school (rereading, highlighting, cramming) with the handful of techniques the research actually supports: retrieval, spacing, interleaving. You won't get a new brain. You'll stop wasting the one you have.
6 weeks · ~30 hours · a working spaced-retrieval habit applied to one real subject
1.Learning How to Learn — Barbara Oakley & Terrence Sejnowski
The most-enrolled course in Coursera's history, and for good reason. Oakley, an engineer who flunked her way through high-school math, and Sejnowski, a computational neuroscientist at the Salk Institute, cover focused versus diffuse thinking, chunking, the Pomodoro technique and procrastination in short, low-production videos. Watch at 1.25x and do the quizzes. The ideas are simple; the course's job is to make you believe them enough to change how you sit down to study.
Free to audit; certificate optional (~$49)
Learning How to Learn on Coursera →2.Make It Stick — Brown, Roediger & McDaniel
Henry Roediger and Mark McDaniel are cognitive psychologists at Washington University in St. Louis who spent careers measuring what works; Peter Brown turned their findings into readable prose. The book is the evidence behind Oakley's advice: why rereading feels productive and isn't, why testing yourself beats studying, why mixed practice feels worse and works better. Read chapters 1 through 4 closely. The "illusion of knowing" chapter alone will change how you judge your own progress.
~$20 paperback
Make It Stick →3.Anki — spaced retrieval on a real subject
Pick one thing you actually need to learn — a language, a certification, a programming framework — and start writing your own flashcards in Anki. One fact per card, phrased as a question, written by you rather than downloaded. Do your reviews every day, even when it's ten cards. The algorithm schedules each card just before you'd forget it, which is the spacing effect from Make It Stick turned into software. Six weeks in, you'll have proof on your own material that retrieval works.
Free on desktop and Android; iOS app ~$25 one-time
Anki →If this doesn't fit you
If you're a self-directed adult tackling a big project — a new career, a language in a year — replace step 2 with Scott Young's Ultralearning. It's less rigorous about the research and more useful about planning: how to scope a project, drill weak points and get feedback without a teacher. Keep step 3 either way.
Why this path
Most people who search for "how to learn" end up reading productivity blogs and buying a new notebook. The science of learning is unusually settled: retrieval practice and spacing beat rereading in study after study. Oakley makes it intuitive, Make It Stick makes it credible, and Anki makes it a daily behavior. The third step is the one that matters. Knowing about the testing effect changes nothing; doing twenty minutes of reviews every morning changes everything.
