Finally he realized he is the king of nothing.
Why do you think he realized that?
He has never been anything and he will never be anything.
While it is not good to think that you are nothing, it is good to reflect on yourself and be realistic on who you are. It can help you become a better person.
I don't have time for self reflection, I need to continue to make myself look like a better person.
Looking like a better person and actually being a better person are completely different. Instead of focusing on the look of it, you should do more to embrace being a better person overall.
