Live poker upswings and downswings, you are going to get more for example in live cash games due to the speed of hands and how that variant is played - MTT wise - i feel its really about the type of games you choose to play and the frequency you play them.
I remember laying down KK first hand once in a live tourney which had a decent buy in, it was made easier by the fact that i was reraised all in and there was a second caller - i would have lost too with QQ and AK showing and a Q on the turn - so i avoided a bullet here and went on to cash and finish 3rd so i look back at that as a upswing in live play and a great decision.
Poker is a game as you know that guarantees very little, we play it for many reasons, some of those reasons are because it is so difficult to master or in fact win at..it requires luck which we yearn for and seek, variance is another word for good or bad luck however you want to term it..
You get times when you are on a heater and are making good decisions and getting the rewards without being sucked out but because there is probabilities involved, every day will be different to an extent - managing your emotions and play is crucial to success.
