Time

What a funny thing time is. Time is the one thing you can not bargain with, or negotiate with. It's the one thing you can't buy more of, or replace. It's also the one thing that can never be taken away from you. How your spend YOUR TIME is your choice, but every minute that passes by is one more minute that you can't replace. When it's gone, it's gone. Nothing you can do will ever change that.

Be careful how you spend your time, who you spend it with, and what you get in return.
