From my own experience I can say that a bad back makes you hike slower, stove-up knees keep you from wading confidently, tendinitis of the elbows buggers your casting, and a dose of giardia can send you dashing to the bushes fifteen times in an afternoon, but although none of this is fun, it's discernibly better than not fishing.
John GierachI know I'm a long way from greatness, but I am beginning to come at it in my own way. I can go through the basic motions pretty well, don't rely quite as religiously on specific fly patterns as I once did, have worked out ways of compensating for some of my most egregious weaknesses and have come to count heavily on timing because it's a hell of a lot easier to catch fish when the fish are biting.
John GierachIt's an odd fact of life that whichever side of the stream you're on, two-thirds of the best water is out of reach on the other side.
John GierachThe best fisherman I know try not to make the same mistakes over and over again; instead they strive to make new and interesting mistakes and to remember what they learned from them.
John GierachSomething to think about: If you fish the wrong fly long and hard enough, it will sooner or later become the right fly.
John GierachI like to do every operation the same way on each fly. In the course of tying a batch of flies, I might get an idea on how to do something differently, but try to save it to try out later rather than break my comfortable rhythm. I don't worry about forgetting it. In my experience good ideas stay with you, while bad ones go back to where they came from, and good riddance.
