It's not the situation that's causing your stress, it's your thoughts, and you can change that right here and now. You can choose to be peaceful right here and now. Peace is a choice, and it has nothing to do with what other people do or think.
Gerald JampolskyGiving means extending one's love with no conditions, no expectations and no boundaries. . . Peace of minds occurs, therefore, when we put all our attention into giving and have no desire to get anything from, or to change, another person. . . The giving motivation leads to a sense of inner peace and joy that is unrelated to time.
