A good manager doesn't aim for 100 percent on projects. A good manager understands how to get to 80 percent and go! When they “go” they are doing so to learn and modify. When they do that, then they can get to 85 percent, then 90 percent.

Managers understand the process of growth.

Of course, managers must limit mistakes and bad plans, but must also stop getting in the way of progress and learning.
