Five ways to remember what you learn

Use it within the week. An idea applied within seven days has every chance of staying; one never used fades within a month.

Explain it to a colleague. Telling what you learned forces you to rephrase it, and rephrasing is how you remember.

Space out reviews. Reread your notes the next day, then a week later, then a month later.

Test yourself rather than reread. Three questions to yourself beat ten pages reread.

Pick one thing to change. One habit kept beats five good resolutions.
