Quality is not an act, it is a habit.
Never complain and never explain.
Well done is better than well said.
If you're going through hell, keep going.
If you've got a talent, protect it.
To know oneself, one should assert oneself.
Wherever you are - be all there.
What you do today can improve all your tomorrows.
The wise does at once what the fool does at last.
The most effective way to do it, is to do it.
The laws of nature are but the mathematical thoughts of God.
