Problems are not stop signs, they are guidelines.
It's always too early to quit.
To be a good loser is to learn how to win.
If you're going through hell, keep going.
Things do not happen. Things are made to happen.
Leap, and the net will appear.
If you think you can do it, you can.
What you do today can improve all your tomorrows.
The wise does at once what the fool does at last.
Go for it now. The future is promised to no one.
They were all famous and fantastic fellows.
