The Law of Attraction dictates that we attract to us from the Universe, that which we think about and feel most.
Therefore, if you feel loving, forgiving, want to spread peace, want to be happy, the world will benefit from that, and so will each individual.
But we need to remember that the same goes for hatred, unforgiveness and fear. So be careful of what you could be spreading.
It is a vicious circle.
Break the circle of fear, and join the circle of love.
Nourish the world with love and starve it of the fear.
