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

To know oneself, one should assert oneself.

What you do today can improve all your tomorrows.

If you think you can do it, you can.

I can, therefore I am.

Never complain and never explain.

Expect problems and eat them for breakfast.

Things do not happen. Things are made to happen.

Quality is not an act, it is a habit.
