Did you ever wish you could change someone's negative feelings toward you into positive ones? Consider the following story:
In the days of Rabbi Chaim of Volozhin, it occurred that a butcher was angry at the Rabbi of his city for rendering a decision that the meat of a cow he wanted to sell was not kosher. In his anger, he devised a scheme to murder the Rabbi. On a pretext, he had the Rabbi travel with him on a lonely road. Along the way, the butcher took out his sharp knife and wanted to kill the Rabbi.
At first the Rabbi pleaded with the butcher to have compassion on him. But this was to no avail. When the Rabbi saw that nothing he could say would make a difference, he started to mentally focus on all of the positive qualities and attributes of the butcher. Suddenly there was an amazing transformation. The butcher began to cry, kissed the Rabbi, and begged his forgiveness.
The lesson: Love others and they can't help but to love you!
