Mind the ... Gap
 

If you find yourself photographing the same things over and over you will start to feel uninspired and lose interest in what you found so stimulating. To get that spark back I can highly recommend joining a photo challenge group. These can be found all over the internet. The premise is that a challenge is set for a particular theme. Some set daily challenges  others weekly or monthly. There are usually rules regarding when the date of the shot must be (usually you aren't allowed to post images that weren't created during that challenge period) or how many pictures you can post. Some even allow the use of video.
 

These types of challenges give you a focus and a reason to get out with the camera and start taking shooting. A great motivator for those times when the enthusiasm levels are on the decline. It's also a great way to get feedback on what you are doing. There is nothing more rewarding that finding out that others like what you've done.
