I realize that I was in wonderful place with wonderful students around me, wonderful teachers. Everything was going well. Except for the fact. That I was unhappy. And I didn't understand why. It was then in a matter of moments that I had to find out why and become happier. And that was when I switched my concentration from computer science to philosophy and psychology with a single question: how can I become happier?
