Sometimes we find ourselves in situations in which we try to make others happy, even though in doing so we neglect ourselves and experience sorrow.
We often do things for the sake of others, even though it is difficult. And if this gift is not recognised or appreciated we tend to get upset.
I will experience the greatest happiness if I give without expecting anything in return. I have to learn to give wisely. When I give with a pure heart I will experience happiness and make those around me happy too.
