It sounds like you need to go back to basics. Throw out your current goals and assumptions. Think through and write down the things you value the most. Based on your values, think through what you want out of your life. Then, compare/contrast with where you are today. Once you have a good picture of this, you need to take a 10-year view of how you are going to get from where you are now to where you want to be. Don't do anything less than 10 years since you'll just want to hurry things up and inherently fail.

Chances are, you already know what you don't like about your current circumstances, but you just don't have the courage (yet) to face it. The exercise above will help you -- it helped me. I'm quitting my day job this Friday to focus on what I love doing.
