Either you run the day or the day runs you.
You never know what motivates you.
Problems are not stop signs, they are guidelines.
To be a good loser is to learn how to win.
Be thine own palace, or the world's thy jail.
Leap, and the net will appear.
The wise does at once what the fool does at last.
The dog that trots about finds a bone.
The most effective way to do it, is to do it.
Do not weep do not wax indignant. Understand.
