I can’t say I really lose interest so much as gain frustration almost exclusively via lack of funds. I sometimes want to quit simply because I can’t afford things. I’m not talking about being mad I can’t buy this years model of something. I mean I can’t afford things like the new impeller for my skimmer or a power head that doesn’t rattle like a lawnmower with a bent shaft. Or new bulbs. Lots of medical bills recently have me bound up financially. The skimmer still sorta works and the water still moves in the tank and the lights still make things happy so I can’t justify to myself buying new stuff. Gotta keep the priorities right! My wife and I still love it and we won’t be broke forever so we will limp it along til then
