This reminds me of a piece of advice from Brian Fox (http://en.wikipedia.org/wiki/Brian_Fox) which is that anyone who wants freedom should get enough jobs as waiters to be confident that you can do it at need.
The reason is very simple. If you are in a strange place in desperate circumstances, an experienced waiter finds it fairly easy to get a job. And very importantly, you get to eat on your first day in the job. This makes it a very valuable fallback to have.
If you're a waiter in a decent restaurant, the food will also be pretty good. Furthermore once your circumstances improve, it is a job that you can leave easily.
(Note that Brian Fox's circumstances have definitely improved. He had a successful startup back in the mid-90s.)
