This is sound advice. It really helps if you can see a product or company that the herd doesn’t see (as in your example of da Vinci, where you were able to see first hand the product they make) and realize that it’s only a matter of time before the rest of the market joins the bandwagon. But aren’t these types of opportunities rare? You really have to keep your eyes open to catch them. Having someone, like yourself, in the industry sharing his knowledge would be a definite advantage to those of us who are unfamiliar with these technological opportunities.
