If you think you can do it, you can.
Quality is not an act, it is a habit.
Be gentle to all and stern with yourself.
It's always too early to quit.
Know or listen to those who know.
Be thine own palace, or the world's thy jail.
Either you run the day or the day runs you.
The most effective way to do it, is to do it.
Begin to be now what you will be hereafter.
Leap, and the net will appear.
I didn't feel any remorse or sympathy if I injured a rival. I went over the top a few times but I never broke anyone's leg.
