To just have experience for different species of trout in different water takes a lot of time. To have knowledge of how to catch many species of fish in various types of water obviously takes much longer and takes away time you could be spending honing in on a subset.
Yeah, but if you get a few other experiences, you'll find advancement in your subset. Some other aspect is more obvious somewhere else, but can be applied. For instance, if you always go to a local brookie stream at 9 a.m. and fish till 2 in early May, and catch about 30, you're fat and happy, and you end up doing the same thing over and over again.
Till you go to a brown trout stream the next day, and the fishing sucks from 9 till 2. But at 6 p.m. things really turned on. Then you think, hmm, wonder what the brookie stream would do at 6 p.m.?
So you try it, and catch 70 instead of 30.
Then comes June. Brookies are still better later in the day. But suddenly, the best brown trout fishing flips to the morning. Why?
Well, holy heck, it's all about water temps. When temps were in the 50's everywhere, evening was great because those were peak water temps. But come June, the temps on that lowland brownie stream surpassed 60, and now, morning is better because it's when it's the coldest. And guess what? Come August and September the brookie one may flip over too.
When you expand it to other types of fish it really puts things in perspective.
Yup. It's not just other types of fish. Even in the trout game there's a difference between limestoners and freestoners. There's vast differences based on gradient and fertility. Water temps. Siltation. Major hatch types. Flow rates and runoff rates. Stream size.
And suddenly your in the Carribbean with some mangroves to your back and you remember the snap cast you learned while brookie fishing.
You learn by exposing yourself to different situations. Then what you learn can be applied to new situations. And suddenly, even though you've never done something, you'd be able to pick it up pretty quickly. That's when you're not a beginner anymore.
It doesn't make you an expert though. Journeyman was a good word. After reaching journeyman status, then you can absolutely perfect one particular thing, and become an expert in it. Nobody is an expert in fly fishing. You can be an expert on Spring Creek, or the double haul, or entomology. But it's just too wide a sport to perfect everything.
