Most important stuff that affect my photography:
1) lack of sleep; If I didn't get at least 9hours of sleep, my photos won't be amazing.
2) Emotions; I take totally different photos depending on my mood. If I just had a fight, my compositions are more in the face. Love makes me look for more romance and I am able to capture more interaction between people.
3) Time between jobs; If you have to shoot for days and days without a break, you will get borred and lazy. Try to keep your intrest on the subject. If this doesn't work, get up early and look at the sunrise. Then take your filmcamera and take 10 photographs. For me this works every time I start to feel my photography is lacking. It's not about what you photograph, but about photographing something else. If it's early, the chance of you seeing something else is much bigger.
4) Time for myself.
I would say take a break and go on a holliday. It's all in the mind, everything is.
