If this happens…
Having a go-to “if this/then…” plan is a great idea.
Because a) humans aren’t great at anticipating unpredictable events, and b) we’re especially not good at confronting the tension than occurs when our best of intentions clash with reality.
Like it or not, most things, most of the time, won’t go according to plan, or as expected.
Things come up—and when they do—it’s best to at least know what to do and what not to. Not because you’ll always need to follow a plan, but because having one—writing one down, planning for the unexpected, preparing for the worst—is a far better way to make it through the world than not having one.
