To be a good loser is to learn how to win.
If you're going through hell, keep going.
The wise does at once what the fool does at last.
Expect problems and eat them for breakfast.
The secret of getting ahead is getting started.
It's always too early to quit.
What you do today can improve all your tomorrows.
Go for it now. The future is promised to no one.
Either you run the day or the day runs you.
Be gentle to all and stern with yourself.
Is it right to probe so deeply into Nature's secrets? The question must here be raised whether it will benefit mankind, or whether the knowledge will be harmful.
