Came here to say this, although in a slightly different way. No matter what your bill rate is, if your commit is for xx hours per week/month, you're always going to feel like you're losing. Especially when you _inevitably_ encounter the customer who gets irate when you could only manage yy hours of brainpower in a week, even if those hours were superhumanly productive (and they probably were, amirite, or you wouldn't have burned out early for the week). In an age where so many people are seeing past the lie of butts in seats for 40 hours a week, don't be the one to subject your own self to the same.
