When you meet people in life, treat them in a way that your absence will be greatly missed whenever you are around.
There are some set of people who do not know how to relate well with people probably because they feel that no one has any value to add to them.
One truth about life is that, you have to make your presence in people's lives a remarkable one. If your presence in the life of a person I'd remarkable, then there is no way that person (who is sane) will turn around to hurt you.
Association with the right individuals brings you peace, makes your life organized, and guarantees success all around.
Another thing is that, you might not know what the future holds for you and the person beside you, so it is better to act well now and make good and beneficial association that will promote better and greater things for you.
