Well, as a psychologist, I can say that for all of us—almost all of us—our dreams don't fit within the 10 commandments; but that is only because we have some serious unresolved motivational conflicts, various complexes, and so on. If a person is doing well, they are calm, happy, self-confident, love themselves, other people, and their work, and they don't worry about tomorrow, but live for today (and the most interesting thing is that this state is much easier to achieve than usually thought); and they don't break the 10 commandments not because they fear God or something else, but simply because they don't want to and feel no need for it. In essence, the 10 commandments are the most basic norms of behavior in society.
It sounds very idealistic, especially regarding the ideal state of a person, but in my opinion, that's how it is.

Oh, I apologize to everyone! I kept writing "10 commandments" everywhere, but there actually are 11 of them!
