Be gentle to all and stern with yourself.
Things do not happen. Things are made to happen.
The wise does at once what the fool does at last.
If you've got a talent, protect it.
Do not weep do not wax indignant. Understand.
Well done is better than well said.
Never complain and never explain.
Problems are not stop signs, they are guidelines.
You never know what motivates you.
Without hard work, nothing grows but weeds.
My talent is such that no undertaking, however vast in size... has ever surpassed my courage.
