To know oneself, one should assert oneself.
Who seeks shall find.
By failing to prepare, you are preparing to fail.
To be a good loser is to learn how to win.
Wherever you are - be all there.
Well done is better than well said.
Be kind whenever possible. It is always possible.
If you think you can do it, you can.
Be gentle to all and stern with yourself.
Only the educated are free.
God sleeps in the minerals, awakens in plants, walks in animals, and thinks in man.
Science already contained all that was necessary, if you just brought it out.
