I should never focus on Theory

Never. It was my mistake. I do without knowing why I do it. It is stupid.
I will not commit it again.
Focus on Questions and Answers. Focus on Reality, not theory.
It is stupid to learn things I will never use. It is really stupid.
Theory is not what I am concerned.

Words are not what I am concerned. I concern about meaning, which guide my actions, give me money, productive.
