Obviously it is important to build on shooting skills as a photographer. There should be an constant effort to produce better and better images. i am a business person as well, so i also have to have a concrete business plan and marketing strategy... or so I'm learning!
I have been scouring the net looking for resources to help me establish the frame work I feel I need. There is a decent amount of info but not a lot of hands on resources that are free or cheep. What I have found though is pretty amazing!(links at bottom of page)
My hope is that in 2013 I will not only be a better and more confident photographer but that I will also be a smarter more organized business woman.
