To know oneself, one should assert oneself.
Things do not happen. Things are made to happen.
If you've got a talent, protect it.
Never complain and never explain.
Either you run the day or the day runs you.
Always desire to learn something useful.
Only the educated are free.
Do not weep do not wax indignant. Understand.
Be gentle to all and stern with yourself.
Begin to be now what you will be hereafter.
The attempt to combine wisdom and power has only rarely been successful and then only for a short while.
