The other day, I discussed the concept of the existence of altruism with a friend. It is an interesting one as being completely selfless, is something that I do not necessarily believe in. We both agreed that there is probably no such thing as being 100% altruistic. For example: I am teaching English to some kids in Bali to help out a friend who had to go back to Australia. My passion is not teaching, I like kids and love to hang out with them, but in general I only committed myself to help out this friend. But now I learn that this experience is helping me to create more structure in my life, that it is really fun to have these kids welcome you with open arms every week and that they are super happy to see you. So where I might have said yes to this commitment out of altruistic reasons, I actually am getting a lot out of it myself.
My conclusion would be that it doesn’t really matter whether altruism really exists; it is about your intention. If you want to help out others in a selfless way, it does not matter that you might get something out of it in the end. That is actually a really good thing.
