Hi all,
here's my story about "entrepreneur".
I served as pilot in the GAF (German Air Force) for 23 years when I retired at an age of 43 years - much too young to go to the park and count birds.
I had little experience in electronics, but lots in aerodynamics and electronic warfare.
Opening an electronics shop was almost desastrous in the small town I lived in. So I looked for a job using my knowledge and abilities.
An industrial fan manufacturer from the UK searched for service personal to take their "Varofoil" fans into operation at the customer's site. Those fans had variable pitch propellers making them useful for air movement in large buildings like hospitals, offices and schools, either for constant pressure or constant air volume flow.
I did a few jobs on test base, found installation errors very quickly and solved the problems.
After one month I received a contract with that company, to continue work with them on my own business risk with just customer's addresses provided and information about the setup the customer desired.
I guess I must have performed well since my company's name (one man company) was traded all over Europe to find hidden construction errors and correct for them for proper function of the entire air movement system - including clean room techniques.
I won't talk about money, but it was more than I ever had expected to earn.
My advice: Find a niche where you can do better than any competitor. (Be prepared for 18 hours of work per day.)
