Did a bit under 6 months for strong-armed robbery in my youth... was young dumb and drunk, saw two others flashing around some cash, gave em a whoppin' and pocketed the money. Ended up getting ID'd hours later with police cruising around the neighborhood. Quite frankly, it put me on the right course, on release I was house arrest for another 6 months + weekly check-ins... got addicted to EverQuest during that time and it kept me off the street and away from a lot of bad influences around.
I did end up arrested again a few years later for putting my step father through a glass coffee table when he smacked my mother in front of me. Was given 3 years suspended sentence and mandatory anger management classes. The classes helped a lot and techniques I learned there I continue to use today, but I'll still go into a blind rage if someone laid hands on my wife or children.
Ultimately, don't recommend it kids. Keep your nose clean, stay out of jail. It's boring, depressing, and you're locked up with far more fucked up individuals... nearly got stabbed for winning a few games of crazy 8s in a row during rec time, they ended up putting that dude into isolation for the rest of my time there.
