Worry comes from the belief you are powerless.
You can change anything about yourself quite quickly. All you have to do is give up the belief system that says that it takes a long time to change.
The understanding of fear cures fear.
If you let other people do it for you, they will do it to you.
Never be afraid to expose a weakness in yourself. Exposing a weakness is the beginning of strength.
You are walking, talking evidence of your beliefs.
