2) Stop calling from the SB, I don't care how cheap it is.
3) Stop open limping, EVER.
4) This is key, you make all your money at micro stakes by betting good hands for value and not paying of hands better than yours. Bluff less, and don't slow play anything.

Your going to showdown way to much. Cbet your missed flops and give up if called. Stop calling river bets
