I recently came across the below St. Therese prayer for self confidence, and have begun copying it into my journal every day. It brings me so much peace and confidence, and I keep on sending it to friends who are going through transitions.
St. Therese
She said, "May today there be peace within. May you trust that you are exactly where you are meant to be. May you not forget the infinite possibilities that are born of faith in yourself and others. May you use the gifts you have received, and pass on the love that has been given to you. May you be content with yourself just the way you are. Let this knowledge settle into your bones, and allow your soul the freedom to sing, dance, praise and love. It is there for each and every one of us."
