expressing myself is synonymous with trying to attract attention to myself. there is no difference. i am a textbook opportunist. i will do *whatever* i can to attract the attention i am seeking to receive the approval i am wanting (a lot of this simply involves the innocent task of earnestly trying to please someone, because pleasing someone turns out to be a good strategy for getting someone to like you). then, when it suits me, i will call this 'expression myself', when really i have little idea what that locution even means.
I would like to think that I express myself through my music, but truth be told that isn't the case at all. The music I create has little to do with me on an emotional level. Simply put, I don't express myself at all.
