Self control isnt the same as
self preservation,though some confuse the two. Self control is what keeps you from endangering yourself and the people around you. People who lack self control like to think of themselves as
living dangerously or on the edge, which is not entirely off, but there's a difference between doing something risky on purpose and knowing what the risks beforehand, and wandering/stumbling your way into it and not knowing why. The same people who brag about living dangerously are the first to want credit for being cautious, they call themselves cautious every time they gain control of themselves, which is something other people are doing all the time, using self-control. It's like being honest, nobody should get credit for being honest, responsible, or using self-control and good judgment.
Self preservation is doing anything it takes to survive, like a snake or a reptile, without any thought about anything else.
