I don't think we ever escape the desire to avoid looking bad - we just recontextualize it. For instance the article is basically making a short vs long term argument - in the short term you might look foolish, but as a result you might produce something of value (which in the long term will make you look fantastic).

So personally I prefer to frame these things that way - it's not that we should want to look foolish for its own sake (obviously), it's that part of getting anywhere in life is taking some risks and developing your threshold for doing so.
