Time is a wealth of change, but the clock in its parody makes it mere change and no wealth.

Time perfects all living beings as well as kills them; it alone is awake when all others are asleep. Time is insurmountable.

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

Have no fear for atomic energy, 'cause none of them can stop the time.

A man who dares to waste one hour of time has not discovered the value of life.

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