Are your goals "mediocre" or "superior" ... according to you???<quoted text>
I assume you thought there was a point in there somewhere.
Oh wait ... now I see it. Your point is that improper speech is but one of the mediocre goals of achievment you have attained for yourself. OK.
I really don't care about grammar being superior or mediocre. If I comprehend what the person is trying to get across in meaning that's all that matters to me.
I'm not a linguist, nor do I pretend to be one.
