The best preparation for tomorrow is doing your best today.
Sometimes doing your best is not good enough. Sometimes you must do what is required.
If I only had three words of advice, they would be, Tell the Truth. If got three more words, I'd add, all the time.
Do your best and let God do the rest.
Be the one who nurtures and builds. Be the one who has an understanding and a forgiving heart one who looks for the best in people. Leave people better than you found them.
I have seen the best of you, and the worst of you, and I choose both.
It is not enough that we do our best; sometimes we must do what is required.
