I'm with you on most of that, but I think this point is a little dangerous:

> Avoid bad habits of sloth,

Willingness to pitch in when hard work really is called for is a necessary and valuable trait, of course. However, working hard when you don't have to is wasteful, and too many people confuse the two.

Sometimes, a natural inclination to be "lazy" is a lot like trying to avoid unnecessary work by being smart. I would rather work for the boss who identified the problem and bought a dishwasher.
