I had some time to think about this alternate reality, where pr@stitution is fully legal in the US.
In this reality, I believe I'd basically be one of those overachievers, not that I haven't achieved anything so far
Between my 1st and 2nd GF in college, there was a lot of heartache and difficulties in regaining focus and so forth. Instead of dating, if I'd simply gone to brothels during that interim, I would have forgotten the 1st gal in a much shorter time. Also, I probably would have gone right back into my studies & work with 100% concentration. Hence, there would not have been a 2nd GF back in school.
And this is the major focus shift.
Due to my newly added intensity, I would have gone for one of those combined MD-PhD programs with the PhD part in something challenging like biomedical engineering where I'd pretty much, be guaranteed to never have any free time between ages 21 and 26 and thus, the brothels would help release steam.
Today, I'd be one of those doctors, who moonlights at a clinic but does consulting work for industry. Granted, it's not some glamorous type of lifestyle but it's still better than most ppl out there. I probably wouldn't care too much for travel and would be content with the things that I do.
Many years ago, the Best Picture of 1999, "American Beauty", telegraphed the message of Happier Abroad to the world.
Beware of long term engagements with AWs, you may find yourself in a coffin.

BTW, despite settling down with an AW, myself, the warning is still in effect.
