Did you ever ask yourself that question? I did. As a matter of fact, I did it many times during my life. Being honest, before I started to write this article I asked that question, and then, decided to start writing. I can assure that, probably, a 99% of the times I asked that question was because something wrong happened to me, or might be happening to me. But, this article is not about me, but about what causes each one of us to ask ourselves that question.
