“Indulging in undirected positive flights of fancy isn’t always in our interest. Positive thinking can make us feel better in the short term, but over the long term it saps our motivation, preventing us from achieving our wishes and goals, and leaving us feeling frustrated, stymied and stuck.” In Aeon Gabriele Oettingen makes the case against wanton positive thinking: Don’t think too positive. (That’s the tagline for my personal brand.)
