evidence: I have a lazy brother who is - lazy to take a bath and brush his teeth - lazy to clean his room, let alone our house - lazy to study - lazy to help others I also have a friend who is - lazy to help others voluntarily - lazy to work hard with a low salary - lazy to go to church because he does not want to meet his ex girlfriend It seems to me, the word "lazy" in Bill Gates' quote is similar to ones I used for my friend. In order to exclude the meaning of "lazy" that I used for my brother, what is the more specific, accurate word instead of "lazy" for Bill Gates' quote?
