If you're using it to filter out employees or companies to invest in, it may be helpful. But if it's advice for people trying to figure out what to do, I think it falls quite short, in the same camp as "do something you're passionate about". I have 2 successful companies (one consulting/services and another subscription business) and neither one is attractive to me for 10 years. I'm in about year 5 for both. I went into both knowing that they wouldn't excite me for 10 years. They both excited me to build though. Entrepreneurs often like the challenge and the process of the build. So having a shorter time frame or commitment is not necessarily a bad thing. Some people are good at, and enjoy, incubating.
