I'd go back to being 16/17 any day; all through HS I was focused on the future, getting through college and so on. I didn't "live the moment" and damn I regret it. Same with college. I maintained dean's list for 4 years and graduated with honors, was hired in a FT consulting position before I even graduated but - really, really wish I just lived a little more. Didn't have a drink till I was 21
. Yeah - I was (and still am) way too reserved
That behavior continues to bite me in the ass ... I wish I was better at dating. The real world is a hellhole environment. Maybe I ought to drive my BMW more ... I kid.
tl;dr, have fun when you can and stop worrying.
"Why oh why didn't I take the blue pill" (to compensate I got a blue car
).
