Watch what happens to people making the choices you’re tempted by. That’s a free preview.

You do not have to run the experiment yourself. Somebody a year or two ahead already made the choice you are considering, and the results are right there, unedited, if you are willing to look past the part they post. The preview costs nothing, which is unusual for information this good.

Think of a temptation you are currently arguing with, then find two people further down that road. Not to judge them. Just to see the ordinary version of where it leads, which is usually less dramatic and more convincing than any warning.
