Memory of happiness
They say that you only know you are happy when you are not.
I kind of agree to that statement. So now everytime I'm walking with a smile, I know i'm not happy at that moment but I'm pretty much living a memory of happiness.
It kinda works for me positively. I don't have to go ranting around with my friends seeking pleasure in mediocracies ! One good incident in the first half of the day fuels me effortlessly till midnight.
