I agree, bearing in mind that to decide is a bit more substantial than just saying it or thinking it - it's an interaction between your thoughts and your actions and everything. I'd say it more as you create your meaning - it might involve things outside of yourself or it might be more individualistic, but it's not arbitrary, and you can have incorrect beliefs about the meaning you are deciding on/creating.
