Are bad beats making me passive? (6max)

[Obliky]

Im having LOTS of bad beats lately..seems like nothing im doing is working blah blah blah.

Anyway, i think the aforementioned beats may be clouding my judgement and i could be getting a tad passive with my good hands. Or on the other hand i could be playing fine and the beats may be making me think im playing badly.

Villian is 36/0/2.5 over a small no of hands.
