I don't know the answer, but I think that if a business jades its employees to begin with then reversing it will be an uphill battle. You won't be starting at ground zero with them; it will take extra and sincere effort to turn their minds. I'm just musing, but I think that maybe there will always be people who are stuck in an industry or profession that they aren't particularly passionate about. The video called autonomy, mastery, and purpose essential factors of motivations, and that rings true for me, as it probably does for most of us. Did the video have anything much to say about passion? No. I think that people who work a job they don't care about are normal, healthy people. Not all of us will love our job. But I think that if you can find a way to give them those three factors of motivation, then they will work harder and your business will be more successful; and, not only that, but they will be happier and more satisfied with their lives. How awesome would that be?
