I am not an especially creative "idea man" or any kind of "visionary"; my sole strength has always been in improved execution or better implementation of things that already exist. This even applies when I conjure solutions to my own problems, as one is often advised to do when mining for business ideas. All I ever want is a better X. I think that suitably describes the vast majority of the economy, and leads to no particular poverty of entrepreneurial strategies. Moreover, it seems that markets are almost always bigger than technical guys think. If everything were as tired, old, and hackneyed as my pessimistic take suggests, almost everything my customers offer would be completely unmarketable and I'd have no business. So, relax. Almost nothing in life is truly original. Just think of something genuinely useful and build it. :-)
