I think it's also a case of not knowing what you are supposed to be doing. This often happens when you are fishing for a new species, or you are on a water you have never fished before.
Years ago, myself and a friend took Jim Gibbinson for a day's bass fishing. We fished two still waters. One of them had large mouth bass in in, the other small mouth.
Jim was given a few small deerhair jigs to fish with. After my friend Brian and myself had had a couple of fish and Jim hadn't, Jim came to the conclusion that he didn't know what he was supposed to be doing. I think it was Brian who told him to relax a bit.
Shortly after that Jim caught a nice bass.
"Got it" said Jim. Now I know what I am supposed to be doing.
Catching that first fish in a new water is always something I regard as a breakthrough.
Mind you Jim got back at me a few days later. After nearly emptying a Natal lake of its trout in about 6 casts, I asked him what the secret was?
"It's knowing the water" said Jim!
Who was about 6300 miles away from home at the time....
