Years ago, I used to drive by a golf course where several men were playing golf in the middle of the day. Every time I drove by, in the middle of a weekday, I saw them there. Although I had no desire to play golf, I admired their freedom, and began to ask myself, “How are they so free that they can play golf in the middle a weekday? How can they afford to not have a 9-5 job? How have they achieved that kind of independence?”
