The importance of failure

Here's a post via a blogger I've been following a long time, Ms. Jane Galt. It talks about the importance, essentially, of saying yes instead of saying no. Of course there's the argument that saying yes is risky, but in most of the professional situations I've been exposed to (i.e. small programs, small offices, small business), the risks are hardly ever that big. But the risk inherent in pissing people off is rather large.
