Time is the only value to your life here.  You may make and lose and make again many fortunes of material wealth, but you will never regain a minute of your time.  So we only “spend” time in exchange for all things in our lives.  The money will come and go, we can never really spend it.  We can always find a way to get money again, but not your moments of time.  Once spent, they are forever gone.
