how to feel totally confident to yourself?

Just be yourself. Be the best you that you know how to be and don't worry about what others think of you, because it is what you think of yourself that counts and it shows. Think positively! Look, there is always going to be someone who is better at something and not everyone will like you, but if you are being yourself then you can feel confident and secure in knowing that those who call you "friend" really love you for you. There's an old saying, "I'd rather be hated for who I am than loved for who I am not."

Well, first of all, you will have to believe in yourself and trust yourself before you could expect people to do that. We are human being and sometimes might feel down too, but i will not let people see this side of me, i will acted as if im very confident...the more you acted, the more you will feel confident.

Confidence is all an act. If you act confident you are confident. Its as simple as that, because no won is truly confident, if they are, then they are either a fool or just plain arrogant. So how do you feel confident about yourself? Know yourself and know your strengths and weaknesses. If you tell no lies to others and yourself then you have nothing to hide and nothing to be ashamed of. The confidence is shows in your ability to hold yourself strong.
