Very much so true. As far as a job goes, building sites is something I enjoy doing, but I can't say that it's my passion, and being able to work whenever and wherever doesn't give you a sense of structure or stability. It's still a 'job'. Albeit a very nice one, it needs to be done and looked at as such.
The money being taken out of the equation, deep down I'm still struggling to find the one thing to give life purpose. I've looked into becoming, among other things with more human touch, a part time masseuse...go figure. But those questions are probably a bit off topic here at WebmasterWorld... unless that M is for Massage... :)
