Workers of the world, the chains that bind you are not held in place by a ruling class, a "superior" race, by society, the state, or a leader. They are held in place by none other than yourself. Those who seek to exploit are not themselves free, for they place no value in freedom. Who is it that really employs you and commands you to pick up your daily load? And who is it that you allow to pass judgment on the adequacy of your toil? Who have you empowered to dangle the carrot before you and threaten with disapproval? Who, when you wake each morning, sends you off to what you call your work? Is there an "I want to" behind all your "I have to," or have you been so long forgotten to yourself that "I want" exists only as an idea in your head? If you have disconnected from your soul's desire and are drowning in an ocean of "have to," then rise up and overthrow your master. Begin the journey toward emancipation. Work only in such a way that you are truly self-employed. -- Tim Gallwey, The inner game of work

Just like carpentry, measure twice cut once. -- Super-sizing YouTube with Python (Mike Solomon, [email protected])
