Blender changed my thinking about PC’s and my future. I saw my PC before as a gaming machine and a multimedia device but with more capabilities as a console. 
As a kid I had some curious ideas- to become an game developer - but after my first contact with C I gave up I could not understand one word in this little yellow book about game programming what my father have bought me from a local store.   
Since the contact with Blender my thinking about my future and my behavior changed. 
Until that time I don't thought that sitting in front of monitor is a kind of serious work, I thought that crazy scientists are making this "Programs and Games".  My perception of work was to create or build something with tools and materials with hands on it.
But blender changed my mind and my thinking about the whole learning, reading and working stuff and so I bought me my first book of my earned money, crazy XD. 
The next curious thought was to create something awesome whit this crazy open little tool what I have found on the web. I design a homepage in Composer and show my "skills" in creativity a company to get a job/ apprenticeship as a web developer (web development  != Blender 2007 for the common men, I knew in this time a hand full CSS and something about frames and div’s out of MS Frontend era XD. And so I worked Day and Night to make this little guy he is called Moon Robot (http://www.szene1.at/user/K-Jay-O/video/309413) , but my plan failed so I gave up for a while until blender 2.5 came out. 
In time the changes and the engagement I had seen have driven me to get a kind of "High school degree" and basic knowledge about 3D-programs, servers, the communication in the Web, classic design & concept art, programming, network marketing, open source  and many more. 
My motivation: Between the hard work in the construction industry as a drywall assembler and in many more service/production-industrial jobs (until now I had been 20 times employed X/ ) I imagined how people could benefit from this technological-evolution, the cooperation between industries and “style” (ways how people seeing the live and work)  stacks.
I had become with time my personal mission cause of the open Ideas, the economy and creative people with ambitions what stand for what they believe in to use programs based on open technologies inspiration of commercial software for communication between engineers in front of control panels and the mobile Industrial assemblers with work supporting devices in their hands, these teams who would mounting often in dangerous environment would guarantee the best "than" possible result.
