It's not luck it's good angling,
If you think about it how do you improve as an angler if everytime you catch of don't catch its down to luck, good or bad,
it isn't it is down to what you have done well or badly,
I do think there are elements of good fortune, that can help you but ultimately they are things you learn or have learnt to use to your advantage when you see them,
I think there are shortcuts nowadays that make it easier to level up though, everyone now has access to the best baits, sharpest hooks,even decent ready tied rigs, big fish in loads of waters all over the place some more accessible than others, best of everything if you can afford it, I could book a week on Holme Fen or somewhere and maybe obliterate my PB but it wouldn't mean that much to me, I earnt my PB and that's all that matters to me, hopefully I will have earnt the next one too 😁
But we live in a much more instant disposable world nowadays, I still think a 20lber is a big fish, and long may that continue 👍
