Wisdom is such a loaded term. I think the article conflates wisdom with productivity - "To become more productive, do less!" could have equally been an apt title.

On wisdom, I am reminded of the Serenity Prayer- "God, grant me the serenity to accept the things I cannot change, courage to change the things I can, and wisdom to know the difference." (https://en.wikipedia.org/wiki/Serenity_Prayer)
