LEONARDO DA VINCI

1. Greater physical and psychological well-being, superior performance, improved self-esteem, and enhanced relationships.
2. Better stress management. Hopeful people are more ...

That may be true...You either over-estimate yourself or undervalue the talents of the people around you. And as a matter of fact, It will be really painful and disheartening once you know the real truth. "Never think less of yourself, instead think yourself less" 

There will never be a better time to start than right now. You will never feel perfectly ready, and the moment will never be perfectly convenient.

Start working toward your goals. Don't just wait around for someone or something outside yourself to pick you up and carry you forward.
