Only time will tell if it was time well-spent.

Don't waste your time away thinkin' 'bout yesterday's blues.

In rivers, the water that you touch is the last of what has passed and the first of that which comes; so with present time.

You've gotta keep control of your time, and you can't unless you say no. You can't let people set your agenda in life.

Time stays long enough for anyone who will use it.

We must use time wisely and forever realize that the time is always ripe to do right.
