When I was a kid I had model trains. The fun was building. Watching the trains go round and round...Not my thing.
My tanks have been the same thing. I keep building custom parts for this and that. My goal has always been to have a beautiful tank that I don't have to worry about.
I'm an addict (for fish/corals). Years ago I came home from a total wipe out (400g display) and didn't have the heart to get back in. I turned off the lights and everything else - Just let the return pump run and some heaters for almost 18 months. Then found out I had cancer, and decided I wanted a tank so I had something I enjoyed while I was miserable.
There are lots of things in our life that give us joy, as we get older the number of things that do seems to get smaller.
My current system is 1100g, and it's kickin butt. In Nov my Dad got sick and I had to go take care of my parents for 3.5 weeks. When I got back home -- Didn't lose a fish or a coral. It was so rewarding to know that I had built enough little gadgets to keep everything safe while I do other things beside worry about the tank.
If it's not your thing right now - Simplify it. Throw on an autofeeder, keep easier livestock and let the tank just be a tank in your home for awhile - rather than be the tank you always have to make time for.

PS -- Here's the webcam of my tank so you know what I walked away from last month -
