A really good way to counter this, at least for me, is to keep track of your progress in a notebook or on your phone. It helps a lot to be able to say "oh, I was able to do 2 more reps than average this time" or "Hmm, I've been on this weight for a couple of months, maybe I should go up." Plus it's a good motivator -- it's a lot easier to go the the gym when you can see how much progress you've made.
