I wrote another post for The Photoletariat: When and How to Turn Down a Gig "Shooting every job that comes up may seem like a great way to get experience, and when you’re first starting out that may be the way to go. If you are trying to establish a business, though, it’s beneficial to narrow your focus. Know what you do, and what you don’t do, and spend time gaining experience in that specific area. This way you can be great at portraiture, instead of just good at portraiture, and landscapes, and product photography, etc. Also, know your career goals and only take jobs that help those goals. Spending time, money, and resources shooting something that doesn’t help your business doesn’t make sense."
