Time is the most valuable asset you don't own.
Time, like money, is measured by our needs.
Time is free, but it's priceless. You can't own it, but you can use it. You can't keep it, but you can spend it. Once you've lost it you can never get it back.
When you take of a man's time, you've taken a part of his life.
Youth is not rich in time; it may be poor; Part with it as with money, sparing; pay No moment but in purchase of its worth, And what it's worth, ask death-beds; they can tell.
What you don't necessarily realize when you start selling your time by the hour is that what you're really selling is your life.
We can sell our time, but we can't buy it back.
There are some things which cannot be learned quickly, and time, which is all we have, must be paid heavily for their acquiring.
