The difference for me is I haven't experienced what it is like to be good. You know how an olympic gymnast makes insane feats of body control appear easy? I have no idea what that feels like. (and I never will, in my upper 30s I am beginning to lose flexibility needed, not to mention I have no desire to put in the effort in that area.) I don't know what it feels like to fight a 70lb halibut in the north pacific. Sure I can watch someone do it, but to have the skill to do it, to have the experience of catching a massive fish is entirely different than watching someone else do it.

yeah, someone else does it better. (In fact I'm watching Richard Gene the Fishing Machine on Youtube as I write this. I'll never be a fisherman like him. ) The difference is doing as opposed to watching. I have all sorts of second-hand fun watching youtube. But I have so much more fun when I make my own accomplishment. My fish may be smaller and objectively less interesting than the one I saw caught on YT. But the experience of doing is radically different than the experience of watching. I find doing much more engaging.

If I were you I'd look for something that you like to do. Doesn't have to be fishing, that's me. Maybe you like to crochet or program, cook or build. Whatever it is, find something that makes you say "hey, I did that. cool." and go with it. That's where living is!
