Pretty much sums it up:
It’s unlikely that any average student can develop a world-class skill in one particular area. But it’s easy to learn how to do several different things fairly well.
I succeeded as a cartoonist with negligible art talent, some basic writing skills, an ordinary sense of humor and a bit of experience in the business world. The “Dilbert” comic is a combination of all four skills. The world has plenty of better artists, smarter writers, funnier humorists and more experienced business people. The rare part is that each of those modest skills is collected in one person. That’s how value is created.
