It's always too early to quit.

By failing to prepare, you are preparing to fail.

If you're going through hell, keep going.

The dog that trots about finds a bone.

You never know what motivates you.

I can, therefore I am.

Quality is not an act, it is a habit.

Do not weep do not wax indignant. Understand.

To know oneself, one should assert oneself.
