Hygiene, clean cell, mind your business, don’t gamble, don’t do any drugs you can’t pay for up front, and if you get tried, handle it in the moment.
Those six things are key.
Each state has different politics as far as mingling with other races. You’ll want to figure that out pretty quickly. Shouldn’t be difficult to look around and see.
Take one leg out of your pants when taking a shit, especially if in a dorm. Always wear your shoes, never go out into the “public” areas with your shower shoes on. DON’T tell anyone anything that you wouldn’t want every man in the prison to know. Everything comes out in the wash.
Be respectful. Have common courtesy. Please and thank you don’t go out the window in prison.
You don’t want to do anything that will cause you to stand out in any way. Don’t be overly friendly to anyone. Not saying you need to go in and punch the first person you see, but don’t be Mr. Nice guy your when you first hit the tier. Conversely, the guy that comes up to you when you first hit the tier, the one that’s friendly etc? That’s not usually someone you’ll want to make friends with. It’s usually either someone looking to exploit you directly, or someone who is trying to create perceived allies because they’re low on the totem pole.
You are who you walk with.
If someone tries you, stand up for yourself immediately. Don’t let it slide just because you want to “do your time” because that’s how you end up doing MISERABLE time and it’ll likely be worse in the long run. Even if you get beat up, fine. Take it like a man and go about your business. Everyone sees you’ll stand on business and your time will go much smoother.
Think ahead- doing a prison bid is like driving. Be defensive, watch the road, think for other people, foresee problems before they happen.
Get into a routine of self improvement. Work out. Read. Learn a language. Get your GED if you don’t have it. Come out better than you went in.
