The title is sensationalist. The point is that even the best laid plans require an element of luck, so it's better to develop systems of successful habits rather than attaching your hopes and dreams towards a specific "goal". He's not talking about how you, too, can be a comic book artist, he's saying that you need to learn as many useful skills as you can. In his book he devoted considerable time to detailing just how serendipitous the success of Dilbert was. I enjoyed it.
