Begin to be now what you will be hereafter.
It's always too early to quit.
Quality is not an act, it is a habit.
What you do today can improve all your tomorrows.
If you can dream it, you can do it.
Leap, and the net will appear.
Things do not happen. Things are made to happen.
Either you run the day or the day runs you.
To be a good loser is to learn how to win.
The dog that trots about finds a bone.
The doubt of an earnest, thoughtful, patient and laborious mind is worthy of respect. In such doubt may be found indeed more faith than in half the creeds.
