Spot on mate.
I've been fishing for carp for more than 20 years now and I still learn stuff on every trip, especially from blanks (they tell you more than any red letter day will).
Carp angling is a never ending journey imo, we will never know it all, but we can keep learning more and more about the fish and how they react in different environments, and that stands us in good stead to capitalise when they're in front of us. As the journey unfolds we choose to fish harder waters with more special fish as we put what we've learned into practice. As one door closes another opens and our angling evolves. Always learning, always challenging ourselves. It's brilliant because you can never complete it - there's always a newer, bigger challenge. It's impossible to get bored of.
