I love this message. I think that most of the time it's best to have an optimistic mindset about your team and trust that they are doing their best, or at least want to. In my experience, more times than not, unproductive teams aren't the result of people working on the team being "lazy." It's usually externalities like unrealistic estimates, poorly scoped tasks and various company-driven disruptions to the team's focus. And if people are "being lazy", it's usually still an indicator of other problems that have destroyed their morale and a leader should look to fix those things. Otherwise you are trying to treat the symptom, not the problem.
