After having worked for a few employers, then a 4 year stint in the US Army, I decided not to work for anyone anymore. So out of the army I started a pressure-washing business, ran that for 4 years, sold it. Then started a graphic design studio in my basement. After a year, I borrowed money and opened a shop in my hometown doing copying, digital printing, and design. Eventually adding sign making to my services (which has become half my business) - I'm now nearing the end of my 18th year running that.
In the last five years, I took my hobby of drawing homebrew D&D maps, and started creating maps for small RPG publishers and have gotten work from Iron Crown and Paizo. I've created loads of map objects for Profantasy software. And now, through Rite Publishing I am developing, designing, doing some writing, cartography and page layout for my own published setting, Kaidan (Japanese horror) PFRPG. (This was kind of mid-life crisis wanting to explore my love of RPGs and being more of an artist than just a graphic artist.)
So, aside from the Army being more closely aligned with possible wilderness adventure, making a life based on calculated risk, relying on my own talents rather than become someone's employee, one might consider that I might be somewhat of an adventurous spirit.
