I can, therefore I am.

Be gentle to all and stern with yourself.

Go for it now. The future is promised to no one.

Problems are not stop signs, they are guidelines.

If you're going through hell, keep going.

It's always too early to quit.

By failing to prepare, you are preparing to fail.

The dog that trots about finds a bone.

To be a good loser is to learn how to win.
