gonfishn,
I have had that happen & honestly believe that I get a little over confident & think I can then catch fish anyway I want. In other words, I think (at least in my case), that I get a little lazy, lose focus, & fish a little haphazardly. The other side is that when you have to work harder for that first fish, it seems the catching improves dramatically because you've worked & found the key for that day & water.
Just my 2 cents!
Mike
