Perspectives change
and time drops the ball
we all ask for ice cream
and the waiter brings a tall

Dreams don't live in cages,
they can't be watered with wine.
In such a hurry to act my age,
went on stage without my lines.

Everything must rhyme
so keep your colors all inside
and if you feel inclined
be the man we built,
the man who just survives.
I'd change it to "Hit the stage" to better fit the rhythm, but that's about all I would do to improve it.  Great stuff!
