Of the many things you can take away from fly fishing I feel like victory and failure can be the most obvious. However the more I fish the less I look at success on the water in terms of pass or fail and more in what truly gives you that satisfied feeling of accomplishment at the end of the day.
Naturally we are out there to catch fish so days when you don't catch anything can be rather upseting but on the other hand it can either lead you to think more about why you're not getting any action or cause you to seek appreciation more in the surroundings than the activity. Should you change flies, change water, adjust weight, angle, approach, or lengthen leader? When you face these challenges, make a slight alteration and all of a sudden you're catching fish then the lightbulbs start turning on. The more situations like this really the better because it gets you thinking outside of the box and that I feel is what helps you continue to grow as an angler.
The great thing about fishing is it can also be a good blend of skill testing and ethereal moments that seem to throw theory to the wind. Some call it the river gods but whatever it is when you get into those moments when it seems you can do no wrong. It is the pure bliss that will keep you coming back to struggle through a few tough days.
So the best part of all is the more you fish the more you will learn. Unlike many other addictions fly fishing is both the cause and the cure so the best rehab for a fishing addict is to get out and fish...It's good for the mind, body, and soul.
