A very interesting and valuable read is "The Four Hour Work Week" by Tim Ferriss.
While I hold a higher value to "work" than Tim does, I really appreciate many of his ideas.
One of the best concepts is that in today's world you can often work from anywhere. That means you can work from home instead of the office. It also means that you can travel the world and work while you do it.
For the month of May, my wife's work has taken us to Istanbul, Turkey. Thankfully, my job and businesses are such that I can accomplish a lot on the road. In fact I will likely accomplish more in May than I would have if we had stayed at home. On top of that, I can use spare time to visit the wonderful sights of this historic city.
I still need to get better at working while traveling. I didn't bring our VOIP phone, and having it would have been helpful. I have missed out on the ability to pick up the phone a few times. Thankfully between email, Facebook and instant messaging I'm getting the communications I need out.
Where would you like to work from? Is it from home, or around the world? Does your job allow you to do that? If not, what could you do to supplement or replace your income?
