No thing is less stable than the passage of time
  as seconds tick tock one by one.
It moves, but it creeps or it stops then it flies
  and moment by moment it is gone.

A blushing young maid can't wait to be grown,
  a boy wants to shave like his dad.
Time brings the dream, but it's not as it seemed
  and we long for what we once had.

All the stages of life, the children, the wife
  Time steals them away so fast.
The shelves of life's store, from ceiling to floor,
  are stocked with things that don't last.

So we need to learn how to live in the Now,
  not for What Was or Will Be.
Live all of Today as it tick tocks away
  and from Time and it's pain you'll be free.
