Some decisions you can undo like a typo. Others are tattoos. Slow down on the tattoos.

Decisions are not all the same shape, and treating them as if they are is where most of the trouble starts. Plenty can be reversed cheaply, so the right move is to pick fast and adjust. A few cannot be taken back at all, and those deserve a different gear entirely, including sleeping on it and asking somebody who will disagree with you. Speed is a virtue only on the reversible ones.

Before you commit, ask what undoing this would cost. If the answer is nothing much, decide now. If the answer is permanent, wait.
