If you don't work for an employer who gives you a Yearly Review, you should do one yourself. They are really that valuable. The benefit of having an employer do one is you get an objective opinion on your performance. However, taking time to review what worked for you in 2010 and what didn't is one sure way to make 2011 even better.

Consider all facets of your job -- business building, marketing, client relations, client retention, client successes, knowledge base and growth, communication, administrative and keeping your gym and workspace clean. Rate yourself on each. Where could you do better? Where do you shine?

This insight is critical in determining how to better position yourself to grow your income this year. Without a thorough examination of all facets of being a successful personal trainer, chances are you'll fall shor -- as will your clients.
