It took a long time for me to finally take that plunge of leaving the "safe world" behind, and I won't tell you it's always pretty, but success it what we make it. Trying to define success while comparing ourselves to others is zero sum game and there is always greener grass on some side of the fence. There will always be people worse off and always people better off. I just try to worry about me and making due with what I have and focus on being happy. It is what it is, but I know that I'd rather be happy and not living a life I don't want anymore.
