In order to carry a positive action we must develop here a positive vision.
The purpose of our lives is to be happy.
Happiness is not something ready made. It comes from your own actions.
Old friends pass away, new friends appear. It is just like the days. An old day passes, a new day arrives. The important thing is to make it meaningful: a meaningful friend - or a meaningful day.
Our prime purpose in this life is to help others. And if you can't help them, at least don't hurt them.
