Why do I keep making the same mistake?

I can't seem to escape from this self-destructive pattern when it comes to poker. I inevitably get bored playing NLHE, or an irresistible bonus offer comes along, and I get pulled out of my comfort zone into games that hurt my bankroll. I've been playing Rush PLO for a little while now, experimenting with shortstack play after I got off to a rough start with playing fullstacked, and it hasn't gone well at all. I actually got off to a good start with the shortstacking, but then the variance of PLO started rearing its ugly head and I've been in a bit of a nosedive. I don't think I'm terrible at the game but I have a very hard time dealing with the variance. I start to feel uncomfortable with the game and panic at the hit to my bankroll. Since I started playing Rush PLO, I've eaten through about 13% of my Full Tilt bankroll.

So, I'm cutting my losses and hopefully this time I'll learn my lesson. No more screwing around with non-NLHE cash games until both my psyche and bankroll are at a point where I can handle the variance. I'm going to return to 10NLHE, starting with Rush again, to get back in the swing of things and recoup my PLO losses.

At least things have been going decently over at Stars with the 45 turbos. I don't have any stats to post yet, but I know I've been slightly profitable since I started playing them again. Oh, and I do still have a single Step 1 ticket left so my WSOP dream isn't quite dead yet...
