Are stupid people happier ?

Sometimes it is hard to be so intelligent, hard to be smart enough to make the right decisions. I just made the most difficult decision of my life. My heart wanted to say yes but my mind said no, ultimately I went with my mind but I am heartbroken. I know in the long run I shall probbaly be happier but getting through the bad times won't be easy. I sometimes wonder if it would have been better if I had been a little stupid, stupid enough so that I could not think about the future. Stupid enough to just live for the moment and grab any happiness coming my way with both hands. After all who knows what tomorrow holds. For all I know I might be a victim of a hit and run accident on my way to office. Then there would be no me, and no long term.

So are stupid people happier or all happy people stupid ? If happiness is a state of mind does it say that happiness is a form of stupidity. I don't know, but I wonder, I wonder how it would have been if I had been a little stupid. Maybe just maybe I would have held on to my happiness.
