Learning
Learning as an adult happens in the margins of a full life. These essays weigh the methods that repay the time they ask for, and set aside the ones that only feel productive.
How to read this topic
Adults learn in the margins: twenty minutes before work, a chapter on the train, a skill picked up because a job now needs it. These essays look at the methods that hold up under those conditions, and are frank about the ones that mostly feel productive.
The finding they return to most often is that recalling something does more than rereading it. Start with that essay, then spaced repetition, which is recall arranged on a schedule. The essay on note systems is best read last, once you know what you want your notes to do.
