I love what Lioness says and how she says it. Ty Lioness
As for weather you have no purpose in life I cannot say, I've gone back and fourth on this a few times. I always thought what if its reverse, what if we don't have purpose but make purpose of our lives?
One way of thinking about this is think what you'd want people to say about you after your gone. This is where the ego might be helpful. This is something I read in 7 Habits of Highly Effective People.
As for the jobs being rigid and inflexible, many companies are shifting, like Google having 20% self time for self projects and the like. So not all companies fit in that box. In some ways I hate to say it, but you do have to pay your dues, Steve did first with this Game Business, then the first couple of years blogging.
If making money is your goal study money and do finance. A few of my favorites are Dave Ramsey and Clark Howard. Or into stock brokering, or banking. Turn your love of money into a career.
