Go for it now. The future is promised to no one.
Things do not happen. Things are made to happen.
Either you run the day or the day runs you.
By failing to prepare, you are preparing to fail.
It's always too early to quit.
Wherever you are - be all there.
To be a good loser is to learn how to win.
What you do today can improve all your tomorrows.
I can, therefore I am.
Be gentle to all and stern with yourself.
Finish last in your league and they call you idiot. Finish last in medical school and they call you doctor.
You know what they call the fellow who finishes last in his medical school graduating class? They call him 'Doctor.'
