I think this highlights the most important bit that is missing from most checklists... the why.

Yes we have a list of things to do, and we know that if we don't do all those things then bad things can happen, but the most important thing is to know why we are doing those things... Because when bad things start to happen despite following the list, you need to know why you are doing those things so that you have some hope of making it better.
