"If I can stop one heart from breaking,
I shall not live in vain;
If I can ease one life the aching,
Or cool one pain,
Or help one fainting robin,
Unto his nest again,
I shall not live in vain."
When we can help each other then in essence we are helping ourselves. Because the joy it brings to know that someone is less burdened by their lives and uplifted then we are uplifted as well.
