Progress is possible only if we train ourselves to think about programs without thinking of them as pieces of executable code.
I mentioned the non-competitive spirit explicitly, because these days, excellence is a fashionable concept. But excellence is a competitive notion, and that is not what we are heading for: we are heading for perfection.
Interpretation
What this quote means
The quote emphasizes the difference between excellence and perfection, suggesting that the pursuit of perfection should not be rooted in competition.
Edsger Dijkstra points out a crucial distinction between excellence and perfection, arguing that the current trend centers around the concept of excellence, which inherently fosters competition. He asserts that instead of striving for excellence, we should aim for perfection, which should be a personal or collective endeavor rather than a competitive one. This perspective encourages individuals and teams to focus on their own improvement without being influenced by comparative outcomes with others.
Themes
In practice

LISP has jokingly been described as "the most intelligent way to misuse a computer." I think that description is a great compliment because it transmits the full flavour of liberation: it has assisted a number of our most gifted fellow humans in thinking previously impossible thoughts.

People with the best intentions will often give you advice on why you shouldn’t take a risk because of what could happen. While some of what they say may be true, you should never allow them to get their negative anchors into your mind because, like them, you too will begin to sink.
