A second dilemma is when to think again. Before making a decision, it’s worth considering two questions: how high are the stakes, and how reversible is it? If a choice is inconsequential, it makes sense to be decisive: the early bird gets the worm. If you’re about to walk through a revolving door, it’s fine to act quickly too: you can always rethink it later. But if the stakes are high and the door is going to lock behind you, it pays to do your rethinking up front. It really matters, and it won’t be so easy to undo.
