Your relationship with yourself

We all have two selves. Remember the last time you wanted eat high calorie pastry, didn't you split yourself into two selves ? One telling you about the health factors and other telling you about the sensation of hot black chocolate pastry that is about satisfy your dry mouth and taste deprived tongue.

Of the two parts one is logical and the other is emotional. And of the two logical one behaves as senior mature person, while the other one behaves as a child who forces you to do all the crazy things that the logical part thinks bad.

If you are a kind of person that concedes to your "childish" self wishes then you may have found yourself in trouble often. Have you ever thought how your logical self treats you in such situations ?

Do you reprimand yourself for doing such a thing ?
OR
You just calmly tell yourself that you won't do this again ?

Which one of them is better ? Obviously, the second one. Let me know if you feel otherwise via comments.
