Sometimes yes. Sometimes no
What makes you think the only way to have fun shooting is by doing it a lot? I get a great deal of fun from shooting. What I don't get fun from is taking images with no clear goal in mind, because I rarely come home with anything. If I don't see anything worthy in the viewfinder, I don't press the shutter.
I find it fun when I'm working on something planned... the fun for me is finding creative ways to realise a vision or idea. I've got bored of just taking random pictures for the sake of it. I mean.. what am I going to do with them all? After 30 years of doing this, as amateur, professional and teacher... the novelty of just taking pictures for the sake of it wore off a long time ago, as I realised I was wasting time, effort and film
When I do just randomly go snapping, I've stopped using the stupidly heavy and cumbersome D800 anyway. I still rarely come back with more than 5 shots though.
