[Innovation] comes from saying no to 1,000 things to make sure we don’t get on the wrong track or try to do too much. We’re always thinking about new markets we could enter, but it’s only by saying no that you can concentrate on the things that are really important. -- Steve Jobs

Any sufficiently complicated C or Fortran program contains an ad hoc, informally specified, bug-ridden, slow implementation of half of Common Lisp. -- Philip Greenspun (Greenspun's Tenth Rule)

We control complexity by building abstractions that hide details when appropriate. We control complexity by establishing conventional interfaces that enable us to construct systems by combining standard, well-understood pieces in a ``mix and match'' way. We control complexity by establishing new languages for describing a design, each of which emphasizes particular aspects of the design and deemphasizes others. -- Alan J. Perlis

It is practically impossible to teach good programming style to students that have had prior exposure to BASIC. As potential programmers, they are mentally mutilated beyond hope of regeneration. -- E. W. Dijkstra

Why teach drawing to accountants? Because drawing class doesn't just teach people to draw. It teaches them to be more observant. There's no company on earth that wouldn't benefit from having people become more observant. -- Randy S. Nelson (dean of Pixar University)

Quality of the people is better than the quality of the business idea. Crappy people can screw up the best idea in the world. -- Hadi Partovi & Ali Partovi (iLike.com), Talk at StartupSchool2007

Take up one idea. Make that one idea your life - think of it, dream of it, live on that idea. Let the brain, muscles, nerves, every part of your body, be full of that idea, and just leave every other idea alone. This is the way to success. ~Swami Vivekananda

Don’t be afraid to give up the good to go for the great. ~John D. Rockefeller

There are no traffic jams along the extra mile. –Roger Staubach

There are two types of people who will tell you that you cannot make a difference in this world: those who are afraid to try and those who are afraid you will succeed. ~Ray Goforth
