No soul has authority over another. Guidance and straying is a matter between God and you.
In my own case, I realized (albeit a year or two back) that my eating pattern was quite different from what I believed it to be. For a long while I was under the impression that I would overeat when I was in a normal/happy mood..however, it turns out that I am prone to overeating when I am depressed/dejected.
Let's suppose a scale of 1 through 10, with 1 being "utterly broken" and 10 being "on a real high" -- I would then say that at 1 and 2 I would be starving myself, 3-5 I would be overeating, and 6-10 I would be eating "normally".
Why I believe this is important (at least to me) is that it made me realize that I am not in tune with my own self, which basically translates into having no idea even about my own personality, and makes me wonder how much of one's life (= acts/beliefs/choices) is based on an incorrect perception of the self.
....so how well do you suppose that you know yourself?
la ilaaha illaa Allaahu Al-‘Atheemu Al-Haleemu, la ilaaha illaa Allaahu Rabbul ‘arshil-‘atheemi,
la ilaaha illaa Allaahu Rabbus-samaawaati wa Rabbul-ardhi wa Rabbul-‘arshil-kareemi
there is no god except Allah, the All-Mighty, the Forbearing; there is no god except Allah, the Lord of the Mighty Throne;
there is no god except Allah, Lord of the heavens, Lord of the earth and Lord of the noble Throne.
