"Ceaseless optimism about the future only makes for a greater shock when things go wrong; by fighting to maintain only positive beliefs about the future, the positive thinker ends up being less prepared, and more acutely distressed, when things eventually happen that he can't persuade himself to believe are good."

Whenever you start-give it your best. The opportunities are there to be anything you want to be. But wanting to be someone isn't enough; dreaming about it isn't enough; thinking about it isn't enough. You've got to study for it, work for it, fight for it with all your heart and soul, because nobody is going to hand it to you.
