Unix Philosophy

For the love of everything good, please, please please read and understand that philosophy.

In all my years of programming, I have found that when I adhered to the philosophy, my job was easy, and I could build greater and greater things. When I deviated, I found my job boring and routine because I always had to go back and fix things.
