Confidence enables us to interact in social and work situations, enables us to stand up for ourselves, or stand up to the microphone. Confidence allows us to ask for what we want, and allows us to say when something's wrong. Confidence is a starting point to make our dreams become reality, to try new things even if others think we're crazy. It lets us feel proud of what we believe in.
Confidence is the must for everyone's life to get success. We need this in our every part of life. For eg. if you want to learn a new subject, then you should have confidence until you have understood that one. We can say confidently that Confidence is the secrect of sucesss in many people life.
