Hell yeah or no is a situational tool for when overwhelmed by too many options, not a constant life approach everyone should always use.

the tool is used when you are overwhelmed with too many options. You've said yes to too many things, and you need to raise the bar all the way up so that almost everything doesn't pass the bar. It's a tool for a certain situation so I rarely use it. I would not call it a approach to life that everyone should use all the time.
