Lazy is a lack of motivation, if you really want to break it down. There are many "lazy" who work all the time, and part of that is because they don't have the motivation to push forward. Though I don't want to sound as I'm putting those people down, because they're not truly lazy like those who simply give up. But what I'm trying to say is that there are people who are rich because they couldn't take the 40 hour grind and did something about it, while others accepted it.
