The thing about fishing for me is that it's about exploring the lake and relaxing. It ain't called "catching" for a reason.
But I don't really do catch and release. I eat what I catch (provided it's a legal size/species of course). I feel like catching fish just to catch them is kinda a dick move.
People don't go out to the woods and shoot a deer in the leg and walk away. So why should we put a hook in a fish's lip/throat just for giggles?
Fishing is an old way for introverts to be socially acceptable. Want some time alone with your thoughts? Go fishing. Doesn't matter if you catch anything.
