The hardest part of design ... is keeping features out. -- Donald Norman

Always dive down into a problem and get your hands on the deepest issue behind the problem. All other considerations are to dismissed as "engineering details"; they can be sorted out after the basic problem has been solved. -- Chris Crawford

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

I find that the harder I work, the more luck I seem to have. -- Thomas Jefferson

If you don’t value your time, neither will others. Stop giving away your time and talents- start charging for it. ~Kim Garst

We must believe that we are gifted for something, and that this thing, at whatever cost, must be attained. –Marie Curie

In order to succeed, your desire for success should be greater than your fear of failure. –Bill Cosby
