don't be afraid..

.." First, be willing to accept that you are not perfect, and that you make mistakes. Shrug them off, and get on with the rest of your life without allowing them to influence your feelings or self-confidence.
Second, be calmly and confidently observant of the things that happen in your life, and realise that a mistake does not mean that you are a mistake. In fact, if you are succeeding, you are probably making far more mistakes than anybody else.
Just go with the flow...."
