The difference between one who fly-fishes and one who is a fly-fisher is.... a flyfisher fly fishes.
If one gives up on flyfishing when conditions are high, low, cold, warm, windy, off-color.....how would one ever learn to fly-fish when it's high, low, cold, warm, windy, off-color...
I started with a spin rod as a kid, but picked up on fly-fishing and fly tying early on. I spin fished and carried a fly rod as a back up. After a while I fly fished and kept my spin rod handy as a backup. Before too many years passed, I no longer carried any spinning tackle and a second fly rod was my back up.
It wasn't until I began to fly fish under all conditions when I started putting things together as a flyfisher.
Graduating from The School of Hard Knocks is both a humbling and rewarding experience.
There's no shame in getting skunked....hopefully you learned something that can be used next time out, or when you find similar conditions on some future trip.
No one evers learns it all, or even most of it....but it's the trying and the small victories that help one move forward that are most rewarding; for me anyway.
