Most of the decisions I have agonised over were reversible, and most of the ones I made quickly were not. That is an uncomfortable thing to notice about oneself, but I suspect I am not the only one. It is easy to deliberate at length over the choice of tool or the direction we could change next quarter. And then we commit to the acquisition, the architecture, the move abroad, on the strength of an afternoon's enthusiasm.

The distinction worth internalising is between doors you can walk back through and doors that close behind you. A two-way door decision should be made fast, with incomplete information, precisely because the cost of being wrong is the cost of walking back, which is usually modest. A one-way door deserves the opposite treatment: slow down, gather more, talk to people who will disagree with you, and accept that the deliberation is genuinely worth what it costs. The failure mode is not that we are too careful or too reckless in general. It is that we apply the wrong mode to the wrong door.

What makes this hard in practice is that the sorting itself requires judgement. A decision we are excited about tends to look reversible. A decision we dread tends to look permanent. So the honest question is not how it feels but what it would actually cost to undo: in money, in time, in relationships, in reputation. Ask that first, then decide how much care the decision has earned. So, as a reflection for today: which door are you standing in front of right now, and are you treating it like the kind of door it actually is?
