Got what it takes to freelance?

John Hewitt wrote a post called "Are You Determined Enough to be a Freelance Writer?" He discusses how freelancing takes some serious determination and constant hard work. With a healthy amount of determination, one can work through stuff like this:

• Finding work when you don’t have any
• Promoting yourself even if you’re shy
• Writing when you don’t feel inspired or energetic
• Staying productive despite a hundred minor distractions
• Completing assignments on time even when you have a good excuse not to
• Taking assignments that aren’t interesting
• Finding ways to improve as a writer
• Learning, learning, learning
