While I agree that it is a good post, isn't it kinda obvious that if you are an idea person, can execute on that idea to make a product and also sell it, you are king of the world? I mean, you have everything except finding a way to repair your brain and body towards immortality (which I am still not quite sure if desirable)...
If there are 1000 people who are 'idea people', 100 of them can execute on an idea; actually build something. 10 can get that thing sold.
Those 10 are the dangerous ones.
Great post.
