Hi
"When I leave here, you will have lost your grey frowns and defensive negativity and you will actually want to come to work. And that will do a lot more to help you and the community you serve than a pat on the back and some more bullshit about how policing is all about people."

Here's some definitions of "that will do" which I found on the Web.
1."said to mean that you do not want any more of something" (Source: Cambridge Dictionary)
2. "that is enough, that will suffice" (Source: thefreedictionary)
My question is how should I get the meaning of this phrase in the context that I provide? I would like to know if these definitions exactly express the idea of the sentence above or there's an another meaning.
Neither of these meanings are the one you need here. Here "That will do more" means "That will achieve more" or "That will produce better results".
