How should I stop thinking that I am even slightly enlightened?

I don't know how else to phrase this question, but please advise. I have this constant irritating feeling that I am kind of enlightened. It is confusing. I don't really know if it is my ego which is trying to assume this sort of "super self", when in reality I am just a normal person, making normal mistakes. I become unaware of my mental formations sometimes, or careless about what I say, or I get angry at times. A little more about this. I know about this ultimate goal, like Nirvana or Moksha or call it anything. I listen to talks by Ajahn Brahmavamso, Alan Watts, J.Krishnamurti and some other yogis. Then I think my ego blends into acting like that enlightened being. I sometimes advise my parents on some matters also. It is definitely weird. You see I want to achieve that final goal, but I accelerate towards it in a moment. It definitely seems wrong. Or is there a final goal at all? It seems like I am constantly checking myself against enlightenment. It is funny too. So please advise. And also I would like to know if there was any such situation(in the texts) which the Buddha faced.
