When the sun is shining we are happy. When there are clouds we are sad. We are very much influenced by our surroundings. Reach out to others more and more, even if only by wishing them well. Gradually we will cultivate strength and courage to remain happy regardless of outside influences. We will be less influenced by what others say of us and how they treat us. Our hearts will fill more with love rather that revenge and reactivity.
