Confidence is being able to say 'I'm good enough' without feeling the need for anyone else to tell you.
Don't be satisfied with stories, how things have gone with others. Unfold your own myth.
Believe in yourself and all that you are. Know that there is something inside you that is greater than any obstacle.
The way to develop self-confidence is to do the thing you fear and get a record of successful experiences behind you.
Optimism is the faith that leads to achievement. Nothing can be done without hope and confidence.
