Poetry may make us from time to time a little more aware of the deeper, unnamed feelings which form the substratum of our being, to which we rarely penetrate; for our lives are mostly a constant evasion of ourselves.
The best thing is to always keep honest people around, because when you have a bunch of yes men around that know that you're making a mistake but let you go on with it, that's when it ruins your mind state as an artist.
