If you enjoy photography, a good logical step is to try and make money from your hobby. Then you can spend more time doing what you enjoy. Selling your photographs takes time and dedication, but it is possible. Lots of people do it, and you can too. Almost every professional photographer started out in some other field: Elliott Porter was a doctor, Ansel Adams was a pianist, Galen Rowell was a mechanic, Bob Krist was an actor. I am still a Business IT Advisor but you never know. If these people can start from nowhere and sell their work, so can you.
The nice part about selling photography is that anyone can do it -- you're not dependent upon physical ability, age, or background. It's more about art and energy. The photographic market is so open that every photographer and publisher I've met is pleased to give ideas and suggestions.
