> 114. Your needs come first. Then come those of your co-workers. Both come before that of the customer and before that of your manager. You need to be healthy, learning about the task at hand, improving your mental model of the product, and building a theory of how the code works. Otherwise, you aren’t going to be able to address anybody else’s needs.

I really like this. As always, the devil is in the boundaries (masseuses at work and limos to/from work are not "needs") but the basic principle is right: if the employee isn't in good shape, they can't serve the customer, which is how they serve the business.
