Every habit follows a three-part loop: a cue, a routine, and a reward. Understanding this loop is the key to changing habits.
Study for 15 minutes every day after dinner. Once the habit is established, increase the duration.
Attach a new habit to an existing one. If you already brush your teeth every morning, add a five-minute review of your schedule right after.
Make good habits easy and bad habits hard. Keep junk food out of your room and healthy snacks within reach.
