There is nothing right and wrong in this world, whatever we feel is right as per our perception is right and whatever we feel is wrong is wrong. We have been taught certain things and we feel these things are right or wrong. The one notion which we are taught is that we should not be selfish however the truth is who is not selfish in this world. Everyone is, even the greatest philanthropist cause is selfish enough. We don’t do anything in this world which is not for self. We do charity not because they need it, but because we want to help others, now look at this scientifically, we did what we wanted so it gave happiness to others, and that is why we are associated with those causes which are close to our heart not with every cause. We goto temple, not because God wants us to visit, but because we want to worship him for ourselves, whether it is out of fear, our desires, to ask for wishes, to ask for enlightenment or whatever, still we are doing it because we like doing it. We take care of our children because we feel they are our children, whatever amenities we have given we feel, that our children should have those. So whatever we do is for self and we must take the responsibility of that or else we would feel we have obliged others, and this way our expectations would keep rising from others which will eventually hurt us, but if we understand one small thing that it’s done for us, it would be easy to keep our expectations lower.
