Here's some ideas on things to do while one works over time to improve self esteem:

volunteer helping others

learn a new skill

improve an existing skill

do something to improve your appearance buy some new clothes, have your hair cut or colored, etc. (Sometimes “look good” = “feel better.”)

make your home more comfortable or more “you”

reduce your stress (easier said than done—ask your therapist for tips)

be kind to yourself; do something nice just for you

use positive self-talk; stop negative thoughts

avoid negative people

seek out people who like and respect you

avoid activities where you are sure to fail (don’t set yourself up for failure)

find activities you are likely to succeed at

try to have a sense of humor about yourself

make a list of things you really like about yourself

make a list of your accomplishments
