I enjoyed this article and think it's good advice, and I also think that the punchline (title + last sentence) is wrong. Not that it makes a big difference, I just treasure texts more that I feel the author thought through to the last detail.

If you don't design your career, in most cases I guess no one will. In the comments are good examples, like the random walk of the drunken sailor. The cases in which you could use the phrase "someone else designed it for me" in a meaningful way seem rather rare to me.
