What am i doing wrong? - Blind steals at 3/6

[IGMorton]

What am i doing wrong with my blind steals at 3/6? When i filter my PT stats for my attempts to steal i show a profit of only .015 BB / hand, which has a negligable impact on my win rate (.0015 BB / 100). Either i'm wasting a lot of mental energy playing marginal hands or there is room for improvement post-flop. All i can figure out is that i'm seeing showdown a bit too often.

Att. To Steal Blinds: 40.95%

Steal Success:
No flop %: 28.7
I Fold %: 26.0
WwoSD %: 47.3
WSD %: 26.7
W$SD %: 49.3

After a blind steal raise, i generally autobet the flop. The players at 3/6 aren't terribly agressive blind defeners and rarely get tricky. When they bet back at me, they usually have something (often top pair).

Turn play:

If i have a pair or better, oesd, or flush draw:
-if he checks, i usualy bet.
-if he bets turn, i usually call.

If i have nothing on a scary board:
-if he checks, i usually take the free card.
-if he bets turn, i usually fold.

River play:

If i have bottom / small pair:
-if he checks, i usually check behind. if it looks like he missed a straigh/flush draw i bet.
-if he bets, i fold unless he's really agressive

If i have 2nd highest pair:
-if he bets, i usually call
-if he checks, i check behind if he raised on the flop or turn. i bet if he just called down.

If i have top pair or better:
-if he bets, i raise if i have good kicker, call otherwise on an uncoordinated board
-if he checks, i usually bet

I really have trouble when the river card makes 4 flush or 4 connected. My hand reading skills aren't great. But at party 3/6 people do such silly sheit...
