Why Am I So Results Driven?

[Jazza]

changed over from UB to Party about 5 days ago

i started off on track winning about 10BB/100hands (no limit) but then took a downswing and barely stayed above breakeven for about 5K hands, i was pretty sure it was bad luck

during this time i began to question my abilities and begin to think that maybe my style is no good at Party and I really am just a break even player

now just recently i hit an upswing and my results are coming much closer to what i expected (about 9BB/100hands) and now feel overconfident, like it's only a matter of time before i'm playing about 4 limits higher than my current limit

so here's the thing, i know the math, i understand the variance (for me about 4BB/100hands after 7K hands) but my confidence in my own abilities still waxes and wanes over near meaningless numbers

and since having confidence is needed to play well, this effect can amplify my swings, increasing my variance

do any of you guys have similar problems? any tips to help steady myself?
