"Give a man a fish and feed him for a day. Teach a man to fish and
feed him for a lifetime. Teach a man to cycle and he will realize
fishing is stupid and boring."
"Why do you go away? So that you can come back. So that you can see
the place you came from with new eyes and extra colors. And the
people there see you differently, too. Coming back to where you
started is not the same as never leaving."
-- Terry Pratchett, "A Hat Full of Sky"
