If there's a single lesson that life teaches us, it's that wishing doesn't make it so.
It’s no use going back to yesterday, because I was a different person then.
In the end, we only regret the chance we didn’t take.
Yesterday is not ours to recover, but tomorrow is ours to win or lose.
Lyndon B. Johnson
Until you value yourself, you won't value your time. Until you value your time, you will not do anything with it.
M. Scott Peck
You only live once, but if you do it right, once is enough.
