Of course you need to be what you are, just avoid acting like an inventor as you seek to monetize your ideas. Act like a businessman and you'll go much further much faster. If you can't do that then you need to find a partner you can trust who can "think like a businessman". Trust me on this cuz I've been there and done all of that.
I have a couple of business degrees and I work in business so at the very least I have some training to do so. I guess by that you mean to just avoid all of the pitfalls mentioned in that article.
