Why is it so difficult to love?
More often than not, people are not ready to express what they feel. It is this that makes them stay away from the love. You do not have to be so busy in life that you never let yourself love other beings. Love can be for anyone. It can be your pet, your friend, sister, brother, parents and others.
You have to attempt to get away from feelings of jealousy, hatred and revenge. Such feelings tear you apart and make you ill as well. Instead you should forget the hurt that has been given to you and learn to forgive and forget things that do not make you happy.
