How to stay happy
I think about happiness a lot, and more specifically, how to manage my own.
I came up with a formula, which i'm sure millions of others have thought of too, and it's perhaps wrong, but.. i find having a simple model enables me to manipulate my life to maximize happiness.
Happiness = Reality - Expectations
It's a lot easier to manipulate your expectations than reality. So basically for everything I do, I try to expect it to fail and result in disaster. Sometimes it does, at which point reality matches expecations and i'm feeling neutral about it. If I succeed, then it is more of an unexpected pleasure and I am happy. Of course I'm human and my expectations get raised a lot, which leads to unhappiness... but I try to keep it in check as much as possible.
Set the bar low, you'll win every time.
*NOTE: getting some flak for this one! keep in mind, this is how i've modeled MYSELF. I'm not saying it works for everyone... just for me.
