I'm not quite as free as you guys, but I own my business and I'm setting it up so I don't have to work much. Truly, I'm trying to be at the office "working" 2 hours per day. The rest is me reading in my office, meeting with friends in the name of "networking," going to the gym, bullshitting with my employees (which costs me double!), gardening, meditating, hanging with my three small kids.
I'm never retiring if it stays like this :)
