“full of oneself”不是指“满是自己”，而是真含义是自以为是； 目空一切。

【例句】
If you were not so full of yourself, maybe you would be able to stop and observe and see that people don’t even listen when you are talking about yourself.
如果你不是自以为是，也许你能停下来观察，看到人们甚至没有听你自己讲什么。

She's a good-looking woman, but too full of herself for my liking.
她长相虽然好看，但在我看来太过自恋了。
