To know oneself, one should assert oneself.
Problems are not stop signs, they are guidelines.
Be gentle to all and stern with yourself.
The dog that trots about finds a bone.
To be a good loser is to learn how to win.
By failing to prepare, you are preparing to fail.
Do not weep do not wax indignant. Understand.
Only the educated are free.
You never know what motivates you.
Leap, and the net will appear.
The laws of nature are but the mathematical thoughts of God.
