I have an idea...why don't you let D3 be your teacher, hmmm?
Self confidence starts with the belief in yourself PS. Pick something you know you are good at. Have the confidence to do or say what you need to do. Failure is absolutely a possible outcome but that is what makes us even better, even more knowledgeable....
These things will not define you. If you need something to define you, let your D3 do it. I wanna be her when I grow up!!!
