I can, therefore I am.

By failing to prepare, you are preparing to fail.

Be gentle to all and stern with yourself.

The most effective way to do it, is to do it.

You never know what motivates you.

If you're going through hell, keep going.

Do not weep do not wax indignant. Understand.

If you've got a talent, protect it.

To know oneself, one should assert oneself.
