I'm not starting my life over, but I am taking the initial steps to start the next stage of my life. I've been in the corporate world for 20 years and am starting to produce my own products (Literature and multimedia). My goal is to transition over time rather than a drastic change instantaneously.
Why? I have a vision of what I want out of my life and part of that is to be able to personally create for others, not just produce for the corporate environment.
It's not exactly what you asked, but I thought you might be interested in adding a 7th option. "Personal Growth" or "Personal Journey"
