There was a brilliant quote in the film 'The Wedding Crashers' that I saw recently and it went something like this - We have no way of knowing what the future holds for us, all we can do is act based on what we know now. It's going to be fine, your whole life is going to be fine.
I'm sure that's not word for word right but I just love the sentiment behind it, it makes me feel all warm and fuzzy :-)
