players who lose money in 6max usually do so because of post flop play. i didn't become regular winner at 6max until i learned and applied two things postflop:

2. learn how to control the size of the pot. play big hands fast for big pots and small hands slow for small pots. do you really want to play for stacks everytime you have TPTK? against some players, sure, but against others, almost never. this includes learning when to check, when only a better hand will call and a worse hand will fold (and if that player is likely to call your pot sized river bluff w/ marginal holdings like 2nd pair). further related to this is learning when to give an aggressive player enough rope so that you can induce a bluff attempt. when your read indicates that he'll take a stab at a hand in which you have marginal holdings, you have to be more willing to make tough calls. being aggressive is paramount to success in NLHE in general, but learning when to check and call is what is going to round out profitability in your game.
overall, 6max is all about post flop reads, and you just have to keep going through the reps until you get better at it. when you have gone through enough situations, you start to be able to use your experience to your advantage and it becomes more instinctual than conscious decision making. keep plugging away, in the meantime, your bonus project should give you enough captial to stay afloat until you get better post flop.
