Premature abstraction is an equally grevious sin as premature optimization. -- Keith Devens

[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

W. Dijkstra

Everything that can be invented has been invented. -- Charles H. Duell, Commissioner, U.S. Office of Patents, 1899

It is not what you do for your children, but what you have taught them to do for themselves, that will make them successful human beings. –Ann Landers

Knowledge is being aware of what you can do. Wisdom is knowing when not to do it. ~Anonymous

Either write something worth reading or do something worth writing. –Benjamin Franklin

Opportunities don’t happen, you create them. ~Chris Grosser
