You can change schools, cities and usernames. Your habits come with you.

A fresh start changes the audience rather than the person walking in. Habits are portable, and so are the reasons you built them, so whoever was late and defensive in one place is usually late and defensive in the next one inside a month. New surroundings buy you time and the benefit of the doubt. They do not buy change.

Pick one habit you were hoping a new situation would fix, and work on it where you are now. Keep it small enough to measure: up on the first alarm, homework before the phone, apologising the same day. One thing changed in place beats any amount of starting over.
