Who seeks shall find.
Leap, and the net will appear.
What you do today can improve all your tomorrows.
It's always too early to quit.
Always desire to learn something useful.
Be gentle to all and stern with yourself.
Things do not happen. Things are made to happen.
Begin to be now what you will be hereafter.
If you've got a talent, protect it.
The wise does at once what the fool does at last.
Words of wisdom are spoken by children at least as often as scientists.
