Things do not happen. Things are made to happen.

I can, therefore I am.

If you've got a talent, protect it.

By failing to prepare, you are preparing to fail.

If you're going through hell, keep going.

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

Quality is not an act, it is a habit.

Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.
