What are the most best tips to survive in prison?

We have answered this questions many ways in previous questions. It depends on what survival means to the specific inmate.  Prison is what you make of it. It can serve as a beneficial learning experience or it can be a living hell. Every inmate has a choice. An inmate can survive prison by simply following prison administration rules and respecting both officers and fellow prisoners. Offenders can make life harder on themselves by refusing to follow the direct orders of officers, but it's their loved-ones who worry about them. Prison officials have a place specifically for all problem offenders. Unruly offenders are housed in special maximum security cells (also known as the SHU or the hole) reserved for those inmates that won't follow the prison rules.  New inmates often feel the need to fit in. They seek friendship from just about anyone in prison. Choose your friends wisely; the fewer, the better. Mature-minded convicts who mind their own business and follow administration rules are probably a new inmate's best bet. Hang around inmates who have productive hobbies or who go to religious services; who just want to do their time and go home. Stay independent. Conflicts in prison are inevitable, you are housed in an environment of convicted criminals of every type. If you come across a situation where an other offender is giving you a hard time, try talking to him or her. Be respectful. There is absolutely nothing you need to prove so don't feed into their hostility. You are not a coward for avoiding a fight. You are in fact brave if you are able to approach the offender alone. Yes, make sure the offender is alone and calmly and respectfully explain to him or her that you have nothing against them and that you would like to apologize for anything that may have offended them. Trouble-making inmates are more likely to create a conflict for others to see than alone or isolated where there are no witnesses. Talking calmly to an aggressor may neutralize their aggression towards you. It is rare that this respectful tactic will not work. If it does not work and the offender persists, calmly walk away and avoid any eye contact with him or her. Ignore any insults and resist the urge to respond. It takes more will-power to resist a fight than it does to actually throw a punch. Walk away knowing that you are strong. You will one day be a free person after you serve your time. These are some good starting points for keeping it together once you are in. Please feel free to ask specific questions relating to this subject matter.
