People are talking them out of it because the way they word it sounds like there's no reward. They don't need or want more money -- they don't have trouble working harder when needed -- they have no generalized motivation issue or mood issue that would affect their quality of life. So... they're not working harder because they don't want to? I mean it would be like asking "how can I deep clean my house every day" and then explaining that you never have visitors, you find your house fine as it is, you have had no health or sleep issues, and you really only go a week between cleanings. It's a caliber of problem where I guess there's drugs for that, but it's also not really a problem in the first place.
