The Myth of Selflessness

Is that not just the most cynical title you've ever read? Considering the title of my blog it's hardly likely that this is a problem for anyone now is it? If it is a problem for you let me know, so I can laugh at you. Now, to the cheery business of calling you all selfish cunts.
Selflessness is the act of performing an action that offers no benefit to you, and is in fact often detrimental to you, purely for the benefit of others. A fairly simple and certainly honourable cause to stand for, but think about this: if you enjoy acting selflessly, does the fact it makes you happy not therefore mean it can no longer be called selfless?
Maybe an example would help, so imagine yourself in this situation. Someone you care about texts you late at night, clearly in a bad mood. You stay up to try and cheer them up, but appear to be getting nowhere. Now you're losing sleep and almost certainly dragging your own mood down to try and help someone else, you're not the reason they're unhappy so have no obligation to help. It's a pretty selfless way to spend the night is it not?
So why do you do it? We all know the answer, it makes us happy to see the people we care about being happy. So when you go out of your way to make someone else happy, are you doing it for the sake of their mood, or your own?
You may come across as the loveliest fucking thing there is, but in reality we're all as selfish as each other. Don't get me wrong, you are still doing good, still helping others, but it is done for the sake of the person performing the action not the one benefiting from it.
