How do you stay safe and limit likelyhood of getting caught?

Hi guys, I was just wondering, I think the chances of me getting caught is very low, but I’m not sure if it’s 0. Do you guys worry about getting caught? How many ways it’s possible to fuck up? How do you keep safe? Best practices to not get caught? Probabilities of getting caught with your current set up? And can you bring down the chances of getting caught to 0? And also what is a general/fundamental rule/practice you use to not get caught?
