Don't ask 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.
--Howard Thurman, civil rights leader

If you want to build a ship,
don't drum up the men to gather wood, divide the wood and give orders.
Instead, teach them to yearn
for the vast and endless sea.
--Antoine de Saint-Exupery
