> "Some decisions are consequential and irreversible or nearly irreversible — one-way doors — and these decisions must be made methodically, carefully, slowly, with great deliberation and consultation. If you walk through and don't like what you see on the other side, you can't get back to where you were before. We can call those type-1 decisions. But most decisions aren't like that — they are changeable, reversible — they're two-way doors. If you've made a suboptimal type-2 decision, you don't have to live with the consequences for that long. You can reopen the door and go back through. Type-2 decisions can and should be made quickly by high judgement individuals or small groups. As organizations get larger, there seems to be a tendency to use the heavy-weight type-1 decision-making process on most decisions, including many type-2 decisions. The end result of this is slowness, unthoughtful risk aversion, failure to experiment sufficiently, and consequently diminished invention. We'll have to figure out how to fight that tendency." > — *Jeff Bezos, [Amazon.com Shareholder Letter, 2015](https://www.sec.gov/Archives/edgar/data/1018724/000119312516530910/d168744dex991.htm)* A helpful rule of thumb is to make reversible decisions as soon as possible, and irreversible ones as late as possible. Rarely do we face something as permanent as crossing the Rubicon. Can you spot some reversible decisions around you that you're postponing — choices you could treat as hypotheses instead of commitments?
