You are, and you don't have to. Relax, you'll get to that point where you'll seek out complexities because you'll want to know more, but you don't have to.
Dry flies are easiest, its yea big and that shade? Find something thats close as you can, and fish the crap out of it. Eventually you'll learn it was a BWO, and then you'll learn again it was an emerging dun, and then you'll be able to cover that with 2983028 different patterns with subtle differences in design of the wing. Or, you'll just fish the crap out of that yea-big-that-shade fly.
"But, they're taking nymphs!" Fair enough, fish a hare's ear or a pheasant tail. It'll do wonders for you. "What size?" Meh. Who cares, they're fish, they eat food. Its food, right, they eat it. "But, I want to maximize my chances!" Oh, well, I guess that's pretty reasonable. See that thing in the air, go ahead, try and pick a HE that'll be about the same size. (brushes hands clean) "No way, dude, I want more." Fair enough. Carry the basics, apply them when it just seems Right, and when you're done you can consult your copy of the
Meck Pocket Guide to PA Hatches when you get home so you'll know what sort of things to expect when you see a yeah-big-that-shade fly go by your head.
There is an advantage to adding more and more as you go along, as long as you keep your head above the figurative water while you do it. Knowing you can expect BWOs, and what a BWO is, and what the nymph looks like (and even how it acts) can be extra helpful because you know a wee little PT or HE in a sort of olive-y shade can be a better match that one that's full on brown. It helps to know this, but its not essential, because fish will respond to things they think is food.
Will they become selective and turn their noses up at that which they find different? Sure, lots of people say so, and I won't aruge because I don't know any different. However, unless you want to get mired in minutae, you can choose to add to your repository of knowledge each time you go out, rather than jump into the deep end.
Shameless self promotion by way of additional reading.
