As I scrolled through the day's photographs, I knew that something was missing. 

I had just returned from a Meetup where I had a great time photographing Annapolis Harbor. We went there frequently because I really enjoyed shooting the quaint town.

But this time was different. I was underwhelmed with what I photographed that day. The pictures were okay, but I wasn't excited. I had been in a creative rut for a very long time. 

As I would learn a couple years later, it was because I was making one big mistake. Once I found that mistake and corrected it, my energy levels and creativity increased dramatically.

What is it?
