The hunger will give you everything.  And it will take from you everything.  It will cost you your life and there’s not a damn thing you can do about it.  But knowing this, of course, is what sets you free.*
Hugh Macleod

Problems don’t really care whether we acknowledge them or not. They still exist. What matters is how we choose to direct our energy, because our tomorrow is the direct result of the way we spend our resources today.**
Seth Godin

… but this one is;
We have to make sure we focus our energies
on the problem we are here to
make a difference
with:
Where our deepest joy meets
the world’s greatest need.^
