This whole article was light on hard content, but had some great ideas expressed well. For example:

Professional managers—MBA CEOs—are not very creative or adaptable, and their skills don't suit a startup. Business is like a multidimensional probabilistic chessboard.

expresses an idea that most can't articulate well, but seems intuitively true.
