" The loan department of Wells Fargo Bank had a similar experience. When they invited a customer to come into the bank and describe how a loan had changed their life—how it allowed them to buy a house or pay off a debt—it had a dramatic effect on the motivation of bank employees to help more people do the same. They could see for themselves the impact their work was having in someone’s life. This is a significant shift in how the employees perceived their jobs and it is foundational to having a sense of purpose in the work we do. Without necessarily being aware of it, many of the employees stopped coming to work to sell loans and started coming to work to help people. Further proof of how much the quality of our work improves when we can attach a human being to the results was seen in a study that found that simply showing radiologists a photograph of a patient led to a dramatic improvement in the accuracy of their diagnostic findings. Adam Grant conducted another study on lifeguards at a community recreation center. "
