I happened to visit the Dalai Grandma the other day and found she had a great quote for me:
Don’t ask yourself what the world needs. Ask yourself what makes you come alive and then go do that. Because what the world needs is people who have come alive.
Here’s another nice quote from Wikipedia:
…community cannot feed for long on itself; it can only flourish where always the boundaries are giving way to the coming of others from beyond them — unknown and undiscovered brothers.
