Steve Jobs said in this interview I watched that he only hired A-level people. Not B, not C, only A. Only the best. It works because 1. A people never really get a chance to work with people equally skilled as them, so they love it, and 2. Once a group of A people have been put together, they only want more A people in the group, so in a way the organization as a whole checks itself and its not just up to him to hire the right people.
I think I’m going to take this idea with music. Only work with A people
