I don't really have any regrets tbh. Only regret wrt poker I have is probably that I hadn't started at age 18 instead of 21. 2-3 more golden years would have indeed probably settled me for life.
I'm also going to uni atm, though in math and not law. 3 years general math, then 2 years pure math followed by 1 year of financial and actuarial engineering if things go right. The big switch was pretty much black friday for me, despite not living in the USA. I loved ftp, software, blindstructure, lobbies... everything really. Did a bit of stars and partypoker but meh. Moved back home when I called it, no regrets. Tbf I'm not sure how I would do in the current poker economy. Stars is pretty much only site with decent action, and turbo's are low traffic and long wait lists. Hypers are more traffic but also wait list. I'm not the type of person to sit in line and wait for fish. I think I only opensat like sub 5% of my ten thousands of games altogether. I'd just look at lobby and play whoever I wanted. With the current lobby and cartels and what not I'd go mad. Or broke from playing regs 24/7 trying to bust their roll and mine in the process due to rake.

Maybe I would have adapted better than I currently give myself credit for, I'm not sure. I probably would've swapped to hu or 6max plo by now I reckon. Quite love that game. Chicagory mentioned that people still are crushing wrt profit, which could be possible, I just don't see it as have been a viable option for me given the current situation. Even if I didn't go to uni: burned out/bored (you have no idea how happy I was first day at uni that I HAD to get up at like 7am instead of just staying in bed because you can), no more awesome ftp, twiddling thumbs waiting around in line, etc. REALLY really not my thing, so I honestly don't believe I missed out on it (apart from maybe like a year after black friday, I didn't play much then anymore). I'm actually quite happy grinding some spin&gos right now. The bingo element keeps me sharp. ^^ Gonna try and see if I can get supernova with them next year while making some money on the side. I mean, I'm not settled for life, that's not a secret, but just making like $1k-$2k a month from casually playing some week nights or weekends when I don't have anything else to do is quite enjoyable.

tl;dr: no regrets of quiting given current poker economy; regrets of not having time machine to start 3 years earlier than I have

We don't always agree, and I guess not entirely here haha, but I think you'd of done well if you kept playing, assuming you could keep up the motivation and interest (huge if for players, even some of the very best over the years that disappear relatively overnight).

But if you kept that up, there's no reason to think you wouldn't maintain being one of the best $200-500 regs for years, and you'd do fine fighting regs out of your lobbies to get access to bad players.

I mean, you played/hunted plenty of weaker regs when you played, today's environment is not so different in that regard.

In general I have the attention span of a fish. I used to have a new hobby every couple of months. It's been surprising that I managed to keep playing poker for that long. Then again there was always something to strive for. Once I played vs what I considered the best at hu sng's (livb etc), the motivation and interest surely went down already. So yeah, don't think I would've made it because of that.
