Having said that, when you love others, do not expect them to love you back. Instead, you should be optimistic about your life, and extend positive energy to others. When other people sense a positive energy and attitude from you; they would possibly reflect back positive energy to you. When you expect things from people, you limit positive energy towards you. Positive energy does not need instructions to come to you. It is already there (in the world); all you need is to be open, flexible and be positive/and permissible and ready to accept the world as is.
