I built a freelance career from scratch, but it took me about 18 months to really gain momentum. One reason I finally got my freelance feet under me was that I started specializing in health, fitness, nutrition, and bridal (I'd recently gotten married and had a slew of story ideas) subjects.
Specializing made me work more efficiently and create a memorable identity as a writer--so much so that my first book, Ready, Aim, Specialize, was written to help freelancers develop their own lucrative writing niches. So it's not surprising I just posted about Six Reasons to Specialize on Ebyline's blog for freelancers.
Coming soon: advice for every would-be entrepreneur; writers to avoid--and why; and another royalty statement, decoded.
