I ran across an interesting link that relates to colleges and their goals, as well as measuring this goal: http://www.linkedin.com/today/post/article/20130509131339-17000124-congratulations-college-graduate-now-tell-us-what-did-you-learn
It’s disconcerting to see this as a parent of a college kid, but I think this also can apply to work. You ought to think about what you've learned at work on a regular basis. If you're not learning, then you're adding another year of the same experience.
At the end of five years, do you want five years of experience, or one year of experience five times? Employers, and especially technical interviewers, are getting better at separating these out.
Work on your career by learning more. Assess yourself, and try to determine if you’ve learned to actually do new things each year. Make a list, or keep documentation when you learn something new and can apply it to work.
You should ensure your branding reflects this.
