Never complain and never explain.
Always desire to learn something useful.
To know oneself, one should assert oneself.
What you do today can improve all your tomorrows.
To be a good loser is to learn how to win.
Wherever you are - be all there.
The dog that trots about finds a bone.
Quality is not an act, it is a habit.
Be gentle to all and stern with yourself.
I can, therefore I am.
Now it is quite clear to me that there are no solid spheres in the heavens, and those that have been devised by the authors to save the appearances, exist only in the imagination.
