What to Look for

I was a swindler, but I have reformed.
I was an evildoer and a skunk,
A caviller, a haverer, a drunk,
A wicked man who's callous temper stormed
The way a hurricane of hornets swarmed,
But now I am as gentle as a monk
With lovely pieces of fresh bread to dunk
Into a jug of wine that's just been warmed.

You might not see it in me right away,
But now I am so utterly serene
That those who truly know me and have seen
This transformation are prepared to say
It's clear now that I have become okay.
Once I was bad, distressful, even mean.
