It has been my observation that people get ahead during the time that others waste.

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

There's no other time but the present. Anything else is a waste of time.

Never before have we had so little time in which to do so much.

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.

Time heals, and experience teaches that the secret of happiness is in service to others.
