The weakest point in any plan is the part you were too excited to double-check.

Excitement skips steps. The part you were sure about is usually the part you never tested, and confidence feels identical from the inside whether it was earned or not. That is why things fail in the piece nobody worried about rather than the piece everybody feared. Enthusiasm makes excellent fuel and a terrible auditor.

Find the step in your current plan that you have not actually checked because it seemed obvious. Test that one this week: make the call, read the timetable, try it once. Ten minutes spent on your favourite assumption is the best value in the whole thing.
