Then I worked for a bit again to save money, and quit again and just got back this year from 3 years driving all the way around Africa. 
The people I met, the places I saw and the lessons I learned will stay with me for the rest of my life, and I personally love the life.
I've decided I want to be a travel writer and photographer, because it makes me happy. I have way less money, but I'm happier than I've ever been. I have written a couple of books about my adventures, and I write for a slew of magazines now too.
Do what makes you happy.

And the winter is coming...again. :-(
P.S. Will definitely buy your book, so I can daydream with you.
For me, it all starts with savings. If you really, really want to break out of your current lifestyle, you have to start putting money away, and you have to start now.
It might take 5+ years, but if you want it badly enough, you will find a way.
Keep in mind it's a lot (A LOT) cheaper than you think. Most people spend around $1500/mo for absolutely all expenses to drive around the entire world. 
If you already have a place to live, it's really common to air b n b it out and live off the income from that while you're on the road.
We only get one life. Make sure you're doing what you want with it.
Also starting to get a more serious about planning the next big one!
Videos from all over Africa too - getting bribed in Nigeria, getting stuck in the Congo mud, rolling the Jeep in Uganda -
West Africa has a group of countries that use one kind of insurance (called Carte Brune) and East Africa have a bunch of countries that use one kind (called COMESA)
For central America you buy it for every country that need it (about $15/mo) and South America you can get it for multiple countries, or buy it separate.
Really interesting countries like South Africa the insurance is automatically included in the price of gas.
