A real entrepreneur is able to be or to get salesmen, engineer, finance guy, a marketing guy, etc...
An entrepreneur is someone able to start a company and in a company, you need more than an engineer to build a device, you also need a guy to sale theses devices, a guy to market it and a guy that able to get the capital and do the balance sheet.
Usually finance can be done with time or a mortgage, so we ignore that one pretty often but if you can only build, well if you don't learn the other skills or never find someone to fill theses skills for you, then you can't really start a company, can you?
