Losing Interest

Is anybody else like me in that they are losing interest in working on their cars? I don’t know if it’s just cars are losing interest in everything as I get older. I’m not as old as a lot of you, but I’ve had some setbacks in my life and lately I haven’t even go next to car shows just to look.
I have a 65 barracuda in my garage that I’ve had for about 10 years and when I decided to get things going on this year it’s been one thing after another that’s going wrong and still haven’t got it out of the garage, but at least had it running for a bit. Had the carburetor rebuilt and put back on and it’s still doesn’t seem to be getting fuel into the heads although it’s coming to the carb.
Also I had a car, 66 station wagon that one of our members here in Florida known for his wagons, has had in his possession to work on for me and so far he hasn’t done anything to it, but he used a bunch of my parts for his other projects. He’s had the car three years now middle of January. I’m not sure if I want to try to keep going with him, cut my losses and pick the car up and work on it myself, try to find someone else to work on for me, or sell it.
