There is a famous story told of a man who sent a letter to the Lubavitcher Rebbe wherein it roughly read, “I am depressed. I am lonely. I feel that life is meaningless. I try to pray, but the words don’t come out. I keep mitzvot (commandments) but find no peace of mind. I need the Rebbe’s help.” A few weeks later the man received a reply from the Rebbe. He replied without a single word. Instead, he simply circled the first word of every sentence and sent the letter back.
