Writing is a dream job, but not for everyone. Some writers are hired to write product descriptions for catalogs, and some turn out to be J.K. Rowling. Unfortunately, however, most writers have a better chance of writing product descriptions than they do of becoming best-selling authors.
While successful content writers seem to have an enviable life -- they work from home, make their own schedules and work as much or as little as they please -- the vast majority have a hard time making a living of it. They lack the skills necessary to succeed. Because no matter how talented they are, writing skill is simply not enough. So, if you want to become successful as a content writer, you need a full toolkit of marketable skills.
