Adrienne and I were full-time wedding and portrait photographers before we stumbled into developing tools for photographers. The lessons we learned running a $100k+/year business are all here on this blog, waiting for you to learn. So scroll down, pick a topic or a content type and go nuts.
If you really just want me to tell you what to do first, then you should definitely start with our 30-Day Photo Business Challenge. It's one of our most-loved resources. And it's free. Woot.
