Projecting an air of self-assurance will take you a long way.

Be decisive and handle objections as they come, don't relay on others much and don't look to others to determine if you're acting right or wrong. Do what feels right for you.

You don't need to be rich to have high confidence, all you do need is to be proud of yourself and there you'll go with confidence.

One should be more concerned about what his conscience whispers than about what other people shout.

The sense of your own experience will grow along with your confidence.

Whenever it comes to doing anything. Remember the part about having confidence.
