Programmers Waste Enormous Amounts Of Time Thinking About, Or Worrying About, The Speed Of Noncritical Parts Of Their Programs, And These Attempts At Efficiency Actually Have A Strong Negative Impact When Debugging And Maintenance Are Considered. We Should Forget About Small Efficiencies, Say About 97% Of The Time: Premature Optimization Is The Root Of All Evil. Yet We Should Not Pass Up Our Opportunities In That Critical 3%.

Meta-design Is Much More Difficult Than Design; It's Easier To Draw Something Than To Explain How To Draw It.

The Best Programs Are Written So That Computing Machines Can Perform Them Quickly And So That Human Beings Can Understand Them Clearly. A Programmer Is Ideally An Essayist Who Works With Traditional Aesthetic And Literary Forms As Well As Mathematical Concepts, To Communicate The Way That An Algorithm Works And To Convince A Reader That The Results Will Be Correct.

When You Write A Program, Think Of It Primarily As A Work Of Literature. You're Trying To Write Something That Human Beings Are Going To Read. Don't Think Of It Primarily As Something A Computer Is Going To Follow. The More Effective You Are At Making Your Program Readable, The More Effective It's Going To Be: You'll Understand It Today, You'll Understand It Next Week, And Your Successors Who Are Going To Maintain And Modify It Will Understand It.

Premature Optimization Is The Root Of All Evil.
