Having money could Definately help though π
It would give you security, you could give yourself more time, more bait, less stress, obviously it depends on situation, most top anglers make lots of sacrifice, some have no other commitments, or a job that gives them more time,most seem to put a lot on the line for it, I think even if I did have enough money though these days I still wouldn't have enough time or probably even the desire or the single mindedness, you've still got to have the mental toughness to be able to stick it out, and the ability to be aware your own mental state, to live a good life you need balance, I'm not sure chasing big carp is ideal for that π³
I agree with what you are saying though, there are no guarantees but if someone wants to bankroll me I'll give it a whirl I reckon I could get 2 or 3 nights a week If it was my job π
