Bringing it back to basics

Creative blocks suck. Period. They can be hard to overcome at times and can last for a while. That doesn't mean you should stop shooting though. 

Going back to the very beginning to what inspired you to start your photographic journey could be all the inspiration you need. 

For me it was landscape photography. Although I rarely shoot any, it's the thing that inspires me when I'm feeling stuck. Even if you're unable to shoot it, just looking at photos of your chosen category can do wonders for your creativity.
