Back in the day I would wait all day to catch any fish, now if I dont catch anything within a certain amount of time I either move on or call it quits.
Unfortunately it often does. Sometimes ocean fishing I don't even have a minute to drink a beer because it is so productive, other times I can drink a six pack and not get a nibble.
that depends on the type of fishing you doing, night time cat-fishing does, fly-fishing involves a lot of constant movement and doesn't really try your patience.
