Go for it now. The future is promised to no one.
The wise does at once what the fool does at last.
What you do today can improve all your tomorrows.
If you're going through hell, keep going.
Who seeks shall find.
Things do not happen. Things are made to happen.
It's always too early to quit.
If you think you can do it, you can.
The dog that trots about finds a bone.
Expect problems and eat them for breakfast.
The ballplayer who loses his head, who can't keep his cool, is worse than no ballplayer at all.
