You can't care about making money to play good poker. Playing good is all about decision making.
Sometimes you will play absolutely fantastic and still lose. Maybe you didn't get a statistically normal amount of premium hands and got unlucky when you did get them (AA once in 1k hands and lost to KK as a crude example). It is VERY hard to put together a winning session those days.
And sometimes you'll be the guy with KK cracking everyone's AA
