It's a difference of living your life for passion and not for a paycheck. I worked almost all the time, but it was something I loved so much as opposed to a job that I didn't love, where you're skating in at 8:59 A.M. or 9:10 A.M. and leaving the second it hits 5:00 P.M. If you're assigning a dollar value to what you're willing to put up with as opposed to doing what yields you in this world - I have been a whole lot happier when I've been a whole lot broker. Money doesn't define happiness; it's what you do every day that does.
