In your journal, list three champions of your creative self-worth. This is your hall of champions, those who wish you and your creativity well. Also record encouraging words they have said to you. Even if you disbelieve a compliment, record it. It may well be true.
If you are stuck for compliments, go back through old photos and look for positive memories. When, where, and why did you feel good about yourself? Who gave you affirmation?
Additionally, you may wish to write the compliment out and decorate it. Post it near where you will see it all the time. I post mine on the bathroom mirror so its the first thing I see when I get up and the last thing I see before I go to bed.
