If we assume that such a place exists, it it even desirable to attain it?
Anthropological perspectives have shifted throughout the years from believing that one culture represented the pinnacle of evolution (western, anglo) to the idea that to understand another culture, we must evaluate that culture in it's own context. We may be informed by our own cultural experiences, but we must not allow ourselves to compare aspects of foreign cultures directly in an evaluative manner. In this worldview it is not the case that one cultural model is superior, and another inferior. Cultural anthropologists call this relativism.
What does this have to do with fishing?
Perhaps more than meets the eye. If we assume that what is right for us is right for everyone, (or that what is right for us now will continue to be right for us for the duration of our lifespan) we are in for a shocker.
It is my understanding that in certain weather conditions, it is possible to catch bluewater fish like sails and dorado from the beach in Baja. In contemplation of this fact, I have sometimes made the statement that if I were lucky enough to land a sailfish, on a fly, from the beach, I would quit fishing and do something else with my life. But of course that is not true.
There is no path walked by more than one, and it is to our benefit that this should be so. Even an earnest attempt to duplicate another's experiences, accomplishments, and understandings will be met with the most essential of failure. But this is not something that is to be lamented, it is instead to be celebrated!
My choice as an angler is to be willing to go where the spirit moves me. I have no pre-concieved ideas concerning what my eventual destination will be. I do in fact question on a routine basis what it is that compels me on a visceral basis to go out an harass fish over and over and over and over and over and over and over... and I never come close to an answer. It just seems to ridiculous to contemplate. And yet... so is life!
My opinion is that there is NO reason to fish that can be put into words that another human could understand. You either get it or you don't. As Sir Edmund Hillary said, we do it "because it is there." Being engaged in a pursuit both trivial and profound, we can no more justify our obsession than we can describe infinity. So to assume that there is a universal, sequential order to an angler's development, something that indicates our progress, is as useless as saying painting is art but photography is not.
That is not to say that there is no way to gauge our relationship to the game. We may improve our skills. We may observe the development of abilities, and note that priorities have changed. But these things are as personal as they are subjective. In a material sense, I may improve my casting ability by an order of magnitude, but I will never cast as well as Joan Wulff. I may one day decide that the only way to fish is with traditional Catskill dries...
But then again, I might quit fly fishing all together and just soak worms...
