[Eisenstein]

Imagine the friends you didn't make because you stayed in that one night when you were on the fence about going out. Good thing too -- it kept you out of prison!

I mean, imagining what 'wouldn't have been' is a lot easier than imagining what 'could have happened' because you literally have no idea. You can imagine life without your friend group, but try to imagine a life where you ended up grabbing a drink at Jeffery Dahmer's apartment or any of a million other things.
