Do you fish very challenging waters, or at places where there are tons of fish? Are you discouraged by the difficulty in finding them, or are you bored because it's just too easy?
My local waters see massive fishing pressure by anglers and despicable poachers, so every trip is Rubik's-Cube-tough. With those issues, I'm always challenged. It's never close to boring, so when I catch one, or get on a rare rally, it's cause for celebration. Even only one bite and miss during a trip will feel like a win because it's downloadable info. Something to work with for the next time.
However, if I happened to live 75 miles east, like somewhere in Hamptons, and had total access to the resident's only lakes, I would definitely get bored. I know this because I have access to a few of them because I can fish there as a guest occasionally. When you can close your eyes, cast backwards, and catch a bass, it gets old very quickly. For me anyway. I've actually capped off a day of fishing out there with a night trip to one of my local grinder lakes just to wash off the easy. Once or twice a year at those places shooting fish in a barrel is enough for me.
Do you fit into either category, somewhere in the middle, or has it simply all just gotten old? One of the reasons it stays interesting for me is that I like to go down rabbit holes. I don't like to keep it simple. One day I'll be fishing big swimbaits, and the next I'm fishing small finesse baits. I've proven to myself that I can find fish, so catching them in new and challenging ways outside of my middle-of-the road comfort zone has kept things spicy.
