The more I'm at this the more I'm learning that you need to build up resistance to these swings, because they only get worse as you get better and have smaller and smaller relative edges in larger and larger games. I said it recently on 2p2, but if losing $20K will make you quit poker forever, and that will always be the case, you can never safely move up to 40/80. It's just a 100% sure fire way for you to quit forever, eventually. I used to count wins and losses in hundreds; now I count them in thousands. I'm not sure where I'm going with this, but I felt like writing more and this seemed interesting enough.
Another point I made to Private Joker recently was that as a professional poker player, if you're going to lose $20K, it's much better to do it in a week than a year. The reasons are obvious, but if you think about it for just 3 seconds (and not 10) it seems preposterous. It's completely true though. Breaking even forever is really the way to run yourself out of this game; consistently putting yourself into profitable situations where you can win or lose (relatively) big is the way to stay in it and succeed. I wish someone had been able to explain that to me 3 years ago.
