Small details. I can tell ya story about a soldier who broke his shoelace and didn't fix it, and his bootfell off during the assault on the enemy. Did actually happen?? No I never really heard about that happening however thats just the attention to detail you need to have in life - you need to notice when the weakest link in your chain is about to break and strengthen it. That can be achieved with situational awareness. Being aware of your surroundings with one ear open; and being in your own world of outside distractions. You have to navigate the system to obtain the delta of it, and solve the problem through the crux into completion..
