It starts from within. It starts by learning to love yourself as you are. It starts by learning that you have a sense of self worth that no one should be allowed to take away from you. It starts by understanding that you're no better nor any worse than any other person. Only then will you begin to build up any sort of self confidence.
confidence comes from having a family that loves you. if nobody treats you with worth as a child, you grow up learning that you have no worth as a person. people will say it comes from within, but if you are beat down from a young age, finding that inner strength they all talk about is damn near impossible
Fake it till u make it
That is so true. No one is born confident, they just act it until it takes form. It's like learning anything.
