Love for the work does not always equal performance

Research shows that loving your job improves your creative performance at work by nine percent.

Similarly, there is at most a nine percent overlap between how much you love your job and how well you perform at it. Those who love their jobs may be terrible performers, and those who are miserable at work can be among the top-performing employees.

Still, extrinsic rewards such as pay, status, and titles do nearly nothing to improve people's job performance. So, having employees who care about their job is still your best outcome.
