It's funny that the optimists society want to claim today as their own, and quite typical of them really. Although there is something to be said for making your own luck & persistence as opposed to pure optimism. Emotional attachment to the future is pretty useless. To quote the turtle from Kung Fu panda who is hella wise:
Yesterday is history, tomorrow is a mystery, but today is a gift. That's why they call it the present
How cool is that! Listening to a Will Smith interview with Radio 1 was revealing. He was saying he almost struggles to dwell on & remember bad times. It sounded familiar. Who needs bad times, fun can be made. All we gotta do is go make it. Easy really :)
