Fly Fishing, Fact or Fiction

[puddle jumper]

OK,,
Got my copy of Fly Fishing & Flies and the more I read it "and other thing", the more confused about fly fishing I get,, So my question is this is all this confusion worth it,, One of the things I love about fishing for these little fish is that it easy and fun and the more I read the less those's two things are getting,, So is fly fishing for gills really that much better than good old U/L spinning gear???

Thanks for the input..
