I tend to agree with the others on a couple of points. 1) looking at the work of others can be good for getting new ideas and 2) having nothing new to look at tends to exaggerate the problem rather than give your vision a break.
In the past, I got burned out when I was not doing anything that I wanted to do. I was just repeating what others had done because I though that it was what I should be doing. Only after I abandon that and began to explore my own ideas with no regard what so ever to what others might think of them did I really get back into photography.
Even now I have difficulty if I can't get to the places that I want to photograph (which is often), and that's when looking at the work of others really helps. It may sound contrary to what I posted above, but when I see what others have done it occasionally gives me an idea for a new way to approach something that I've been thinking about for a while but have not found the right way to approach.
This does not help me in the least, but some people seem to have good results when they try to follow set subject assignments. Try going to the local photo club web site to see where they are going or what they have chosen for subject matter. If it sounds interesting try going on one of their trips, or if you're like me and don't do a lot socially in this regard, try assigning yourself their subjects for the month. Like I said, this does nothing for me, but some people do find it helpful.
Regardless of what you do, don't
not do. Get out and photograph whatever you think might be interesting. Then come back and browse what you've done. Before you dump everything and write it off as a loss, go through each and every image and think about it for a couple of minutes. Try to figure out what you don't like about it now. Think about what you thought would be interesting when you tripped the shutter. Think about what would make that interesting if you could go back and shoot it again.
Activity is the key here, at least for me. When I'm idle I'm stalled, but when I'm active, even if I don't get anything that I like, I'm still moving forward, even if the pace is slow
