I can understand that people want the simple answer. The problem is that a set of assumptions need to be made, to create any plan. Most of the time, these assumptions are glossed over, or not mentioned at all. AHA! If you do not challenge the assumptions, then how can you rely on the conclusions?

I point out a very popular [apparently] YouTube channel, and show you how easy it is to overlook vital assumptions.
