If the plan only works when everything goes right, it isn’t a plan. It’s a wish.

Any plan that requires every step to work has multiplied its own risk without telling you. Each stage might be likely on its own, and the chain of them is not, which is why schemes that look reasonable on paper collapse at the first ordinary problem: a late bus, a sick teammate, a file that will not open. Hope is doing the structural work.

Take the plan you are relying on and find the step most likely to go wrong. Decide now what you do if it does. One backup turns a wish back into a plan.
