I tried nude photography...but it really made the models nervous seeing me naked like that.
Seriously though...is it a matter of not enjoying the shooting, or is it that you are not getting the exact results you were hoping for?
If that is the case then it will take alot longer than 3,4,5....12 months to be satisfied with your shots. Its an evolving thing, that can always be improved on.
Look into what your camera can do, or different styles of photography and experiment with them for awhile. If your interest isn't renewed after that, then I really doubt it was there to begin with.
Whatever you decide, at least let it be after some effort. You can't learn it all in a few months. If you move on to a new hobby, will you be mad and give up on it after a month or two if you don't have it perfected? If so then I see a long disatisfied life of "could have beens"
