I can, therefore I am.

If you can dream it, you can do it.

The wise does at once what the fool does at last.

Be gentle to all and stern with yourself.

If you've got a talent, protect it.

If you're going through hell, keep going.

To know oneself, one should assert oneself.

Do not weep do not wax indignant. Understand.

Things do not happen. Things are made to happen.
