I went into this article with a lot of skepticism, but the author has some excellent points. Here's one, as an example.

On dealing with people (in his case, artists): "if...someone isn't measuring up, I have no idea how to convince them to do so. So I look for people [who do]." I.e., don't waste your time on people who are "demanding or confused or slow at answering their email".

Lots of other interesting points!
