I agree in principle, but I feel that you have gone a step past the article. While the author did use the words "mental illness," I felt he was mostly talking about general mental well-being (i.e. how to avoid needing the doctor). To extend your analogy, you don't need to go to the doctor to eat well and exercise. You are correct, however, that a person should seek help if something does break. Further, for some people, it might be beneficial to seek assistance (such as therapy) before things break. To finish murdering the analogy, a nutritionist or personal trainer is probably not necessary to eat well or exercise, but they may be extremely valuable to some people.
