I think you missed the part where he said to leave your job. I've done most of my longer-term (one month) vacations after getting laid off or quitting.
It is, I'm now my own employer - for a very good reason (I'm a programmer, can easily do it, and I realized self-employment > employment on many fronts). When I went to India, though, I quit my job teaching personal self-defense and got a job working at an Italian restaurant when I came back (restaurants are excellent sources of short-term income and have many social/physical benefits that trump jobs in the software/knowledge industry).
