"Am I that immature? Am I a brat? Am I silly?"

I guess it depends on what you are calling "I", doesn't it?
I think one would be better off refering to that entity (or those entities) as "it" rather than "I", something to be observed. Is "it" being a brat, is "it" immature, is "it" being silly?

The first freedom is the freedom from "like" and "dislike", something that I am guessing might best be approached by having an overall "aim" for one's life.
