Agree with your summary, but I am not impressed by the use of "stupid". Maybe "being willing to appear stupid", or "having beginner's mind" or "not making assumptions". But "stupid" is just click-bait. For that matter "laziness" too. Author says "work hard, but not all the time".

But the others (Arrogance, Carefreeness, Beauty, Rebellion, Humor) all seem right to me.
