I am not an investor, but a startup founder. Please don't take it the wrong way, but I would have never hired a person who thinks the way you write. I am sure you are a great person, skilled and experienced technically, and all that stuff. But when you are trying to get a new business off the ground, you basically risk your whole life. If you surround yourself with people who don't share your beliefs and goals, who you can't rely on, who care about other things more than about building a successful business, you are totally doomed from the beginning. There is nothing wrong, by the way, with the way you treat such things. Most people on Earth are not entrepreneurs, so it's expected. The point was that if you think that way, you should never even think about joining a startup (at least not at the initial stage).
Regarding the skills, the motivation is much more important (I believe, at least). Say, if you don't know a thing about software engineering, but you love the industry the product targets at, and you are willing to learn, I would be happy to hire you and reject all the experienced engineers from Google, Facebook and other fancy companies who don't give a damn about the product, regardless of how skilled they are.
