Sand In The Hourglass

Ever feel like your just wasting your time?
You sit there and stare blankly thinking of what to do
But what do you do when the one thing you want, doesn't happen?
You spend all that time, being patient staying calm
Sooner or later, the sand runs out
And there's no more time to wait.
When that time comes, what do you do?
Move on and start over?
Should you give up at all?
