The cognitive science of acquiring hard skills: attention modes, memory, procrastination, and practice that sticks.
Most people never study how to study. They inherit a method by accident. Reread the chapter, highlight it, reread it again, then conclude they’re bad at the subject when it doesn’t work. The method was the problem.
Barbara Oakley failed or avoided every math and science class she could until she was 26. She retrained from remedial algebra to a doctorate in systems engineering, and with neuroscientist Terrence Sejnowski turned what she learned into a course that has taught millions of people. This course follows their material.
Each lesson takes one mechanism, like how attention switches modes or why procrastination is a pain response, and gives you the technique that falls out of it. Mechanism first, because a technique on its own gets abandoned the first time it feels awkward.
Learning is a physical change in your brain. It takes time you cannot compress, and the study methods that feel most productive are usually the ones doing the least.
Written one at a time, each grounded in a primary source.
