Not only that, I didn't really see a concrete suggestion of meaning, in the sense that the article only articulates what activity marginally increases some baseline level of meaning. I don't expect an article like this to actually define meaning, of course, but some anecdotes of what "meaning" actually is to some sample of the working population would have been more helpful than throwing around a bunch of hesitantly low-risk workplace suggestions.
