I know where you live
I have personally never experienced a loss of intrest. I'm 15, and I have been keeping fish since I was 4. When I do start to lose a bit of intrest, I switch things around, and get new fish ect. It always works.
I think most people go through it.
At one point I had 10 tanks running - down to 4 now. I really lost interest when I had a couple of tank disasters and lost my beloved plec collection, 2 oscars and a featherfin cat. Only recently have I got keen again. Even now I something think about selling up - keeping the community tank and nothing else but then the big fish do something endearing (like my oscars 'play' with my son and have him squealing with laughter) and I know I couldn't get rid.
I think there is a balance - have enough tanks to keep the fish you really want and not too many that the maintenance and expense over takes the enjoyment.
Hang in there!
