Al Buhr said that. I have spent the last ten years fishing and casting by this fundamental statement. Not a statement that defines any style or method of fishing. Please allow me to set up what it means this 'Fishing Or Not Fishing'.
Each and every fish species that is the target of an angler, has a certain trigger that gets a bite response. The idea is to know these triggers and then present the lure so it is in "bite mode" as soon as your bait hits the water. This is the first part. The second part is to manipulate the line to make the lure act in it's targeting way.
When we get to the end of what will make the bite happen we start the third factor. The time between not fishing and fishing again.
I don't practice when fishing.
Time moves so quickly when we become good casters. The effort of practice as will as seeking out a quality instructor can make the total difference between good days and great ones.
"Just think about the target and hit the bullseye every time."
