What you do today can improve all your tomorrows.
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.
Well done is better than well said.
It's always too early to quit.
If you think you can do it, you can.
Who seeks shall find.
Never complain and never explain.
God sleeps in the minerals, awakens in plants, walks in animals, and thinks in man.
Science already contained all that was necessary, if you just brought it out.
