To know oneself, one should assert oneself.

Be gentle to all and stern with yourself.

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

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

What you do today can improve all your tomorrows.

Things do not happen. Things are made to happen.

If you've got a talent, protect it.

Expect problems and eat them for breakfast.

If you're going through hell, keep going.
