I am big fan of Pixar. Recently I've read article written by its president Ed Catmull.

Harvard Business Review article

I like whole article, but there were a few sentences that I consider really interesting:

If you give a good idea to a mediocre team, they will screw it up; if you give a mediocre idea to a great team, they will either fix it or throw it away and come up with something that works.

it's OK to hire people who are smarter than you are

There were more, but I wanted to avoid quoting the same ideas that were quoted in blog post where I found the article.
