I think you should look carefully at starting hand charts and play tight ABC poker for a while. Stop playing the "would have" game and concentrate on the theory, not the results. Stay focused and ride out those 40-hand cold card streaks. I know after a run of crap cards that ATo looks like a dynamite hand, but it's not that great and you need to excercise caution. Riding cold streaks is tough, but if you have to fold 40 hands in a row, the most it could cost you is 6BB. That's nothing. You'll make that back in one hand.

Stop limping with non-suited connectors in early position. In fact, fold them. Your post-flop play isn't strong enough to win pots out of position when you don't hit hard (ie the straight or two pair).

Don't call even a min raise with KTo, especially when you're out of position (ie in the blinds). The only situation I can recommend is if you've got position on a very loose PFR'r - like someone who's raising around 25% of hands.

Ditch Axs. It's not profitable most of the time. You'll hit a flush on the flop around 1% and a flush draw something like 5% of the time IIRC. When you do hit that flush, people are usually wary of it and you'll only get payed off from a smaller flush or a donk with a hand they can't get away from.
