In my experience I've seen, the people who are good to others generally face lots of problems in their lives. They face problems firstly #) they help wrong people, secondly, #) they forget what gifts are available to them when they help right kind of people, who actually deserve help. Let's talk about first point, if you help people without knowing them, sooner or later you may be in trouble. Because if they are wrong people, you are directly or indirectly, encouraging them, promoting them -- and you are responsible for them. The worst consequences with it is this, if you are too friendly with them, they may, or they will draw you with them; and try, you to become like them or to be partner in their wrong act.
