That's true, but not, IMO, a valid criticism of the article. This article emphatically does not say that if you do the stuff on this list that you will become successful. It makes the implicit claim that if you don't do this stuff you won't become successful. Remember that those two statements are very different, and the second one is valuable even though it doesn't prescribe a path to success.
