Why do we keep doing stupid things?

I was enjoying playing ultrabullet last night...so I kept going. I played one arena and then another. Three. Four. Inevitably, I pushed myself into a tilt attack.

Why did I do that? It's not as if I'd never experienced tilt before, and it's not my first tilt that was entirely my own fault for overdoing things. I should have stopped after one or two ultrabullet arenas.

I think perhaps it's this: once you establish good habits you can forget why you needed them and end up being a victim of your own success. I thought I was above tilting because I hadn't suffered from it in a while. I forgot that the reason I hadn't tilted in some time was that I'd been disciplined about not overdoing things. A little like how people think vaccines aren't necessary because they haven't had to experience the disease.
