“Produce! Produce! Were it but the pitifullest infinitesimal fraction
of a Product, produce it, in God’s name! ’Tis the utmost thou hast in
thee: out with it, then. Up, up! Whatsoever thy hand findeth to do, do
it with thy whole might. Work while it is called Today; for the night
cometh, wherein no man can work.”

Thomas Carlyle (1795–1881)



“If you're going to try, go all the way. Otherwise, don't even start.
This could mean losing girlfriends, wives, relatives and maybe even
your mind. It could mean not eating for three or four days. It could
mean freezing on a park bench. It could mean jail. It could mean
derision. It could mean mockery--isolation. Isolation is the gift. All
the others are a test of your endurance, of how much you really want
to do it. And, you'll do it, despite rejection and the worst odds. And
it will be better than anything else you can imagine. If you're going
to try, go all the way. There is no other feeling like that. You will
be alone with the gods, and the nights will flame with fire. You will
ride life straight to perfect laughter. It's the only good fight there
is.”

- Charles Bukowski, What Matters Most is How Well You Walk Through the
Fire
