Self confidence comes from not always being right but not fearing to be wrong can some one give you a 3 min speech on this?

Self Confidence is basically having confidence in yourself. You dont always have to be right, self confidence comes in here about knowing you were wrong and learning from your mistakes and utilizing the mistake and turn it into an opportunity to help you in the long run, like my old teacher said Benjamin Franklin didn't event electricity on his first try, and neither will you.
