I dare anyone of you to start acting like me, get lots of dismayed looks from people around campus, even get insulted in the middle of your classes, and see how happy you are most of the time. I really don't mind it, though, because I've found the secret of happiness.
Express delivery is also available.
Seriously, I'm going to give you the secret of happiness for free. Here we go. The secret of happiness is to be happy. That's all there is to it. Let me repeat it to you so you remember.
