QJ is a hand that ends up costing me a lot of money at times. Mainly because I don't fold it when I should.
I tend to limp with it from any position and will fold to any violent raises.
I ended up losing with this hand because I know realise that I should've raised preflop to get rid of the hands I USUALLY lose with, like K2o, J2, and the like.

Good advice, Ripp.
