“One source of frustration in the workplace is the frequent mismatch between what people must do and what people [think they] can do. When what they must do exceeds [their perception of] their capabilities, the result is anxiety. When what they must do falls short of [their perception of] their capabilities, the result is boredom. But when the match is just right, the results can be glorious. This is the essence of flow.”
― Daniel H. Pink
