Not sure if you're being sarcastic or not, but I think this is actually good advice. It's great to be a free-thinker and question things, but I do think there is some (monetary) value in just not asking too many questions, but optimizing to be the best at whatever you're doing.
Edit: to give an example, I probably would have done better in school had I spent less time questioning the education system and more time just accepting it and trying to get good grades.
