If you think you can do it, you can.
The dog that trots about finds a bone.
Well done is better than well said.
Never complain and never explain.
Be gentle to all and stern with yourself.
I can, therefore I am.
Without hard work, nothing grows but weeds.
The wise does at once what the fool does at last.
Either you run the day or the day runs you.
To know oneself, one should assert oneself.
The driver of a racing car is a component. When I first began, I used to grip the steering wheel firmly, and I changed gear so hard that I damaged my hand.
