I think was Charlie Munger that talked about the inversion model to tackle ideas. instead of focusing on making it a success, the question is what would guarantee it to be a failure. and address that first. if the easiest points of failure are addressed , or at least mitigated, only the ones you don't know about might get to you.

the rest is upside.
the hope is that while on the job you find those that you don't know yet, and eventually are addressed. but neglecting the ones that you know is a fatal mistake. a gamble that you want to be getting paid for. if you're just being lazy, oh well, then don't come crying when they knock on the door.
