Existence ≠ Notability := Bad editing experience.

Even if you are yourself, thus in a position to know yourself better than third parties, your judgment is no substitute for reliable sources, especially if they show criticism of your person. But, according to BLP guidelines, you are free to remove criticism which is not based upon reliable sources (this is even encouraged). E.g. suppose that you are a married man who had an extramarital affair and the press reported it. In such a case, it would be in your own interest to hide this information from the Wikipedia article, but it would be probably reverted due to vandalism. I mean: once the beans are spilled, there's no way to take them back. (I don't know if this applies to you.)
