It’s a problem if the design doesn’t let you add features at a later date. If you have to redo a program, the hours you spend can cause you to lose your competitive edge. A flexible program demonstrates the difference between a good designer and someone who is just getting a piece of code out. -- Gary Kildall (inventor of CP/M, one of the first OS for the micro).

We now come to the decisive step of mathematical abstraction: we forget about what the symbols stand for. ...[The mathematician] need not be idle; there are many operations which he may carry out with these symbols, without ever having to look at the things they stand for. -- Hermann Weyl, The Mathematical Way of Thinking

Ne te mets pas de limite, la vie se chargera de la mettre a ta place. -- Darryl AMEDON

Beware of bugs in the above code; I have only proved it correct, not tried it. -- Donald Knuth

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

It's your place in the world; it's your life. Go on and do all you can with it, and make it the life you want to live. –Mae Jemison

I find that when you have a real interest in life and a curious life, that sleep is not the most important thing. ~Martha Stewart

Nothing in the world is more common than unsuccessful people with talent. ~Anonymous

You can never cross the ocean until you have the courage to lose sight of the shore. –Christopher Columbus
