at BYU are basically the exact same person as they were then and/or are in the precise position in life in which I expected them to be.

There may be one exception of a Freshman buddy who isn't as successful as I would have guessed, but basically everyone is precisely where anyone with a brain thought they'd be.

Like the guys in high school who were obnoxious and struggled have been in jail and struggled with employment their whole life. The guy Freshman year of BYU who came from a learned doctor's family is now a doctor and doing well. The genius guy who loved horses owns a horse farm after making a bunch of money in M&As at a big law firm. The guy who was smart but quasi-ambitious has done okay, but not great---in every aspect of his life. Like...everyone is nearly exactly where I would have expected.

Point is: I think that most people are basically who they are by senior year of high school, for better or worse. And while there might be exceptions, exceptions do not a rule make.
