I originally read this in a book about mental models, in which they referenced Jeff Bezo's approach to making choices.
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 these 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 judgment individuals or small groups.

Before hearing about this, I was a lot more risk-off in day-to-day life. I would agonize over choices like “Where should I go next in life?”, “Is this a good friend to have?”, and other similar questions.
After I started trying to apply this model to life, I came to realise that very few choices in life are irreversible in my own life. Breaking off a relationship, pretty irreversible. Moving somewhere, reversible. The changing of friends when you move, can be irreversible if poorly managed.
