Time.

Time controls us
when to get up,
when to go to bed,
when to come into the world,
when to do this and do that.
Time has power over everyone
even those who don't think so
Time is one thing that can be lost but always found.
It speeds up when one is having fun
and slows down when one is bored.
Time makes peoples decisions come faster
or hold out
Time tells you when you are going to leave,
so be wary of how your time is spent
because you don't have much left.
