How do you play your A-game all the time?

By this I mean:
* laying down hands you know are beaten
* respecting pot odds
* only calling with implied odds if they really exist
* playing tight when necessary
* playing loose when necessary
* getting value rather than scaring people out of pots

I've been looking at my last few sessions very closely, it would be easy not to cos I can look at the overall result and simply feel smug that I'm up a few buy-ins. BUT, it should be more.

I don't mind badbeats, I mean, I hate them - but I know that for the 6/7 times I win when I'm 6/7 favourite, I have to lose once. So it's not really a badbeat in the grand scheme. And that's fine.

I do mind losing big pots that I've played badly. Two come to mind today. I 3-bet KK and the 40-0.4 (>100 hands) 4-bet. Three options - call and hope for the set, fold, push. Only the first two make sense (purely read and context, I was sitting there knowing "AA" but....) and I deserved to lose 90bb from my 250bb stack. And another, KQs in a crazy limped pot and KJJ flop it should be an easy fold to the check-raise push.

I think the difference between profit and BIG PROFIT is about sticking to the points at the top. (maybe others I've missed?)

My question is: HOW? Some of you must manage it... and I want to figure it out here at 25nl, even though I'm rolled for 50nl (and almost 100nl!)

Thoughts?
