Everyday life is like programming, I guess. If you love something you can put beauty into it.Donald Knuth
Let us change our traditional attitude to the construction of programs. Instead of imagining that our main task is to instruct a computer what to do, let us concentrate rather on explaining to human beings what we want a computer to do.Donald Knuth
