I did fight for 1k spot as much as I could, although in the end I wasn't focusing mainly on poker, due to personal life stuff and doing lot's of drugs.
I currently quit partying traveling and drugs, and focusing on poker full time.

I would tell young(and present) Harthor to value more personal space. There was a point where I became really popular and always allowed people to enter my house, believing I could just focus on poker anyway (wich I could to certain extent but it's not optimal at all obviously)

Also I gave up the possibility of coaching at a really high rate, to spend that time coaching friends for free. I woulnd't do it again. It happened that since it was for free many of them weren't taking it as seriously as a student who's paying for it would do.

I'm currently not interested in making a lot of money for the money itself, I just think it's kind of my place in the world to play online poker, I believe it's what I'm good at (well currently not that good, but I think I will get back to the top).
In the past also I helped ( not sure if that was actually helping), acquaintances offering them money for whatever they needed. Currently I would donate to causes that I believe in instead of people.

I've always been really positive and thought I would never go through depression and stuff like that, wich happened last 2 years kind of. I guess the main advice I would give to my younger self if I could is to be careful about the people/energies I hang around with, we are humans and willpower is limited, so there are moments of the day that we kinda surrender to whatever happens and in those moments it's convenient to not be around bad influences.
I spent a lot of time on weed wich I would rather use for sports nowadays.

Best exploit against fish It's pretty wide question but I'd say valuebet big when they are stationy is what makes ev go up the most. Also if they are not adjusting and are on the tight side just overexploit the spots in wich they are overfolding.
Reg battles strategy changed a lot during the last years, since preflop game changed. We were all playing too wide/aggro preflop. I got a feeling that some sessions against some we would drop our PFR and vpips close to what's gto but without knowing exactly why we were doing it, just by intuition.

I had friends who would lend me money and stopped playing always thinking ok next month I 'll grind hard and make it all back, but then kept moving and coulnd't find a place I felt really comfortable at. Also was counting on money I'm owed but haven't gotten it back yet and it's kinda difficult to get it anytime soon.

do you think in todays climate with cartels etc players progression is cap or certain players have a ceiling because of it.

do u still find the motivation to grind considering u used to play high stakes?

I think it is harder than it's ever been, and not sure how much is possible to make at husng's, i still think it's possible to make at other forms of poker

It was hard some time ago, currently I'm enjoying although it obviously feels really low
