“A plan is only useful if it can survive reality. And a future filled with unknowns is everyone's reality.”
-Morgan Housel, Psychology of Money, p 63
Danny's take: This is not an absolute statement, but it makes an important point. We often make plans without considering 2nd and 3rd order consequences. We also don't ask, “What could go wrong?” and “What's the worst outcome of this plan failing?” And, importantly, “Can I live with this plan failing?”
There is certainly value in planning even when the plan doesn't go a planned. But we should also be thinking about a plan for if the plan doesn't go as planned.
