Yes, I am, because I made my own happiness the most important goal of my life. I am not religious, I don't believe in hell, heaven, afterlife and reincarnation, so I believe you are given only one life and that is it. So why spend it unhappy, depressed or chasing some unrealstic goal? I'd rather enjoy this limited time I am given in this world. Let some fanatic, zealot or politician chase some "high" goal. I am content where I am. And the more time I spend enjoying my life, the better life I am living - and that is the only thing that matters to me.
The same with me man !
