Don't quit. Never give up trying to build the world you can see, even if others can't see it. Listen to your drum and your drum only. It's the one that makes the sweetest sound.
I don't take success and failure seriously. The only thing I do seriously is march forward. If I fall, I get up and march again.
This, then, is the test we must set for ourselves; not to march alone but to march in such a way that others will wish to join us.
