anyone beaten the rake and variance to go pro at online poker

I’m curious if anyone here is actually grinding out a living playing online poker long-term, not just hitting a heater or two but really handling the rake and the swings. In blackjack, you’ve got clear lines for when you’ve got the edge, but poker just seems so heavy on variance that I can’t figure how folks push through a brutal downswing without losing it. Online especially, where the rake eats into your hourly, I have trouble believing most can make it without either running hot or dropping insane volume.

I’ve been lurking around cash tables out of curiosity but always end up back in blackjack because I trust the math more, if that makes sense. Maybe I’m missing a trick? Anyone here actually doing it for a living and seeing a steady, not just lucky, income? How do you deal mentally with those stretches when variance just crushes your winrate?
