Thats not being selfish, but we try to be secure. But I have learned something in the past years. When I give first I get always rewarded in anyway. Where I give a little or a lot, it works every time I do it. I try always to be secure, but sometimes I can keep it for long. So I need to find different ways and have always to sacrifice something in order to get another. I guess it is just the law of the universe :)
