"Free-styling" with rhymes

I did my first sort of free-style rap the other day on vacation to the East Coast. It went pretty much as follows:

Money is all I've ever thought
But that doesn't mean it's all I've got
I'll have to keep this terse
Because I have trouble coming up with a verse
I'm not very good at saying what I feel
But that doesn't mean I can't seal a deal
Cause I try to be methodical
About focusing on the logical

This got me thinking about rhyming - and I think I might actually start trying to do some poetry.
