HELP! I'm becoming a calling station!

[1outer]

I play either 6max SNG's or 45 person SNG's. When I am playing the 45 person, I can take my time, pick my spots, get away from any sketchy spots as I know there is PLENTY of play before and during the final table.

However, when I play 6-max tables, I tend to push way too much (not shove, just lean on my opponents too much) I see so many retarded plays being made and people running the other one down with middle pair - gutshot straight draw to an opponents 3 barrel bluff. I find myself making no big folds at these 6 handed tables.

What do you do when you find yourself calling wayy too light at an aggressive table, the structure calls for pushing small edges, but I think i am taking that to the extreme, for example calling AI bet on turn with middle pair and small flush draw, Villain holding top pair. Am I correct in pushing these small edges or am I truly just turning into a calling station.
