It's interesting that the trait of unmade decisions is framed in the context of stress.

My experience on the flip side is that a couple of kids I went to school with, who have since been very successful, actually made decisions very quickly. To the point where some must have just been guesswork or ini-mini-miny-mo (although no doubt the fact they were successful means it'll be dubbed as "instinct").

So while I'm still pondering decision 1, they already decided 5 things. Sure, 3 failed, but 2 were good decisions. And since I noticed that in them, I've noticed it in other successful people.

It's not a broad brush assessment, but something to think about. Two steps forward and one back it probably better than one step forward in the long run. So just make the damn decision and see what comes of it.
