I would say that maybe this isnt the sport for you... you are pitting your wits against another sentient creature, there are many environmental factors that will effect how fish feed, temperature, long term temperature stability, air pressure, wind direction, how bright it, is water height, availability of natural food....
Then there is the technical aspect... are you fishing in the right places, are you using the right sized fly in the right colour , at the right depth, is your retrieve correct, is your tippet fine enough is your presentation correct, the lay down of your cast delicate enough...
anyone who goes fishing expecting to catch fish is somewhat naive... sometimes the Gods just arent smiling down on you
