Because when you try to follow your passion, you’re less likely to consider other areas of interest, and less likely to anticipate difficulties. And if you ran into obstacles, you ‘re more likely to loose interest and give up. Following your passion reflexes a fixed mindset, it assumes your interest are stable.
