What are some careers that allow you to travel or work from anywhere?

One career option that allows you to travel and provides great benefits is the military. Granted, I am fully aware this isn't a hugely popular option right now but depending on the field you want to work in or if you want to go officer vs. enlisted, then it might open many doors for you. I would suggest the Coast Guard. Their mission is completely different and they travel to a lot of fantastic places. Contrary to popular belief, the CG travels everywhere including the far North and even Antarctica. I mean come on, wouldn't you want to play with polar bears and penguins too?

I work for a print firm in the UK. I live in London, and my "patch" is Central and South America. In the past I have looked after parts of Europe, Southern Africa, the Middle East and Asia. I probably spend 6 to 7 months of the year overseas, and get to work from home a lot when I'm not travelling. It is great to see all these places, but being away from home this much can drag... Working from home, however, rocks!

If you are interested in medicine, an independent CRA (Clinical Research Associate) is a nice job. This is a job where you travel to doctors nd hospitals to train them on how to do a clinical study and then monitor them throughout the study to ensure they are collecting the data correctly.

Travel can be both domestic and international, depending on which clinical study you are working.

Pay is reasonable.

If you like the city where the doctor is located, go a day early and enjoy he city. At most, you will have to pay for the extra night in the hotel room. On the other hand, if you save the company some money (for example, by staying over a Saturday night), they may cover that cost.

Field biology, either as a career academic or a government researcher. While being one usually requires fairly extensive training (usually at least a graduate degree), you get to travel and work in some of the worlds most spectacular wild places.

Aviation Maintenance, near most large airports are schools that can get you an A&P license and other certifications, allowing you to work for airlines and other companies all over the world that need aircraft maintainers and systems techs.
Downside is that layoffs can come around swiftly, but if you're single, you just get up and move to where there is work.
Military contract work is also an option with aviation maintenance, usually requiring military aviation experience, but has the potential for a lot of traveling and great pay.

Once you see the move Up In The Air you might not want this type of career. I currently travel about 25% of the year and it is beginning to take its toll on me.

I know tons of people who've read and raved about "4 hour work week" - amusingly NONE of them are doing that.

I've traveled/worked a lot (mostly around the US).

- Software: you can code from anywhere with a connection and work-from-home-gigs aren't that hard to find. This is what I currently do... pays well and you literally never need to leave the house for some gigs.

- Medical: EMT's, Paramedics and especially nurses can find work almost anywhere (ski towns! - one of the few "real" jobs). I was an EMT for a while... only problem is different states have different requirements (highly regulated)

- Restaurants: I was a chef for a while - you can work pretty much anywhere. Waiters at high-end restaurants clean up to the tune of $400+/night - not bad for a job that starts at 4 and ends at 11.

- Do an internet startup - be your own boss (working on that now).

- Outdoor education - depending on what/where you want to go (kayaking, sailing, NOLS, skiing)... pay is usually crap (except for skiing where you can get great tips).

- ESL Instructor (English as a second language) - you can work anywhere in the world (including places that speak English).

- Get a degree if you want to leave the US - you can get pretty far in the US without a degree (I have) but virtually every country requires a degree for a visa... if you have won it makes doing most of the above in, say, New Zealand, easy-peasy.
