It's not over until I (you) win.
You have to know what is right for you and go after it regardless of what others say.
Anytime you suffer a setback or disappointment, put your head down and plow ahead.
Just because Fate doesn't deal you the right cards, it doesn't mean you should give up. It just means you have to play the cards you get to their maximum potential.
The only limits to the possibilities in your life tomorrow are the buts you use today.
Your goals are the road maps that guide you and show you what is possible for your life.
