So, I came across this effective focus for improving productivity. You have to want to succeed, and you have to be proactive at cultivating better character habits. Here is the page I am now studying: en.wikipedia.org/wiki/Flow_(psychology). Anyhoo, in my case, I work alone and have to do my own human management. Flow is about having high skill and a high challenge. I recommend any manager to first learn about flow, then cultivate it at work. Respect has to be earned. I am also learning and writing into my action plan more work motivation cultivation. Absolutely, the best things in life are free.
