What do we live for? What is the purpose of our life? 

Victor E. Frankl survived the holocaust by answering these questions during the most difficult time of his life.

Frankl was once asked to express in one sentence the meaning of his own life. He wrote the response on paper and asked his students to guess what he had written. After some  moments of quiet reflection, a student surprised Frankl by saying, “The meaning of your life is to help others find the meaning of theirs.” “That was it, exactly,” Frankl said. “Those are the very words I had written.”

And those are the very words I would've written as well.
