Don't be so hard on yourself TM. If you fish enough to notice the really good times and then know when you are in a slump, it happens.
Last year, I was in a horrible slump from about mid August till mid October. How embarrasing to have all the guys around you catching fish when I could not even catch a cold. Needless to say I did not give up and was rewarded graciously for my fortitude. I stuck to my game and before ya know it I could not keep fish off my line. It's all good. Stick it out, it will pass.
