Decisions split into reversible two-way doors and irreversible one-way doors, and only the one-way doors deserve slow, deliberate scrutiny.

Founder of Amazon in 1994 and of the space company Blue Origin in 2000

If you make the wrong decision, if it's a two-way door decision, you pick a door, you walk out and you spend a little time there. It turns out to be the wrong decision, you can come back in and pick another door. Some decisions are so consequential and so important and so hard to reverse that they really are one-way door decisions. You go in that door, you're not coming back. And those decisions have to be made very deliberately, very carefully.
