Valuing lack of weakness rather than strength

Ben Horowitz has an great post on hiring executives.  My favorite part is:

Valuing lack of weakness rather than strength—The more experience you have, the more you realize that there is something seriously wrong with every employee in your company (including you). Literally, nobody is perfect. As a result, it is imperative that you hire for strength rather than lack of weakness. Everybody has weaknesses; they are just easier to find in some people. Hiring for lack of weakness just means that you’ll optimize for pleasantness. Rather, you must figure out the strengths you require and find someone who is world class in those areas despite their weaknesses in other, less important domains.
