I can't think of a time, place or situation where getting more and better feedback would not be a huge benefit.
It might be as simple as asking your family and close friends some scary but specific questions about your own life.
It might be putting a survey out to your congregation or customers.
It might be asking in a a meeting: What's working? (and what's not?)
Getting honest feedback regularly is going to benefit you. How are you going to do it?
