But all of this is a distraction - at the end of the article, the author speaks about the people who are happy and satisfied in their careers - and broadly it seems like people who have autonomy and a sense of purpose in what they do. I run a small business and broadly enjoy working, so things like the Financial Independence movement don't really make sense to me. More money, less money - this is not the crux of the issue. Engagement and autonomy are some of the keys to a fulfilling work life.
