Self Confidence is faith in yourself.
Don’t worry about the people that don’t believe in you or in your goals. Those people will not be of any help to you as you try to climb toward your goal. There will be people that will laugh at you and mock for the way that you act, but remember all your actions are leading you toward your goal. Individuals who believe in themselves no matter what other people say will do great things in life.
Self-confidence is the product of knowledge. Know yourself. Know how much you know and how little. Know why you know it and how you are going to use it. Don’t try to pretend to act like you know more than you do know. Intelligent people can quickly see through false people who claim to know things.
