What is possible depends on how much work you put in to catch up to the game. I was in the same boat playing alot until Black Friday. I have played sporadically but more for fun maybe 1-2 times a year tops over the course of the last decade, but the beginning of this year I jumped back into the game and honestly, everything felt new, and I also discovered there was way more I didn’t know about poker than I thought I did. I started by putting together a small bankroll, lost 60% right away with a nice combination of playing higher stakes than I should, bad play, running bad right off the bat (front end variance), poor bet sizing, and calling way too much. I took a a break for over a month to clear my head and look back on my play and what things I was doing poorly, kept working on plugging leaks and since then grinded my loss back in the last 9 months to where I got it all back and have been netting a win consistently every month. The smartest thing I ever did was just move down in stakes. I know if you had played stakes like 2/4 or 3/6 NLH as your primary games during the online poker boom, it is hard for your ego to accept that the games are just tougher. Once I moved down, my win-rate went up sharply and I had more buy-ins and a greater volume of hands to play through while still learning. And I am always still learning. But point is, old school players can come back to poker and learn to win as long as you catch up to the modern game where you got every kid and their grandma using solvers
