Be gentle to all and stern with yourself.
Problems are not stop signs, they are guidelines.
To know oneself, one should assert oneself.
If you think you can do it, you can.
Well done is better than well said.
Things do not happen. Things are made to happen.
The wise does at once what the fool does at last.
Do not weep do not wax indignant. Understand.
Either you run the day or the day runs you.
You never know what motivates you.
My talent is such that no undertaking, however vast in size... has ever surpassed my courage.
