Why spend extended time in places where you already know you can catch fish? If you have invested personal time and learning in these locations then you will know their moods, their patterns and the subsequent results – nice one!
Do you want to become a better angler than you already are? Then avoid routine and accept the challenge of what that might mean.
That routine exists in technique, location, time of day, time of year, type of presentation, type of weather, type of thinking…. nobody gets better at anything by choosing the easy road – pay your dues, then collect the results.
