If you think you can do it, you can.
You never know what motivates you.
Leap, and the net will appear.
Things do not happen. Things are made to happen.
It's always too early to quit.
Be gentle to all and stern with yourself.
The dog that trots about finds a bone.
Problems are not stop signs, they are guidelines.
Only the educated are free.
If you've got a talent, protect it.
When a man is no longer anxious to do better than well, he is done for.
