It's a much better quote than the annoyingly common, "Don't write a game engine!"
If you work in games or want to work in games, writing a game engine is a very valuable experience. Probably the best thing you can work on for personal growth.
That said, I think you get substantially more value out of the experience if you've already gotten your feet wet making games with a commercial engine.
