I regularly ask my customers for input and opinions, and I use their responses to build on our strengths and address our weaknesses.
I accept that as a leader I'm going to make mistakes sometimes, and when I do I take personal responsibility; I admit it and apologize for it, and then everyone can move on.
I actually appreciate complaints because they clearly point out problem areas, and I effect massive improvements in both perception and productivity by actively addressing each one.
I teach people how to identify areas in need of process improvement, and I give them time and opportunity to create solutions. This keeps my operation running smoothly at all levels.
I prioritize everything in order of importance, and I get things done at the right time by making sure everything on the "most important" list has been addressed before moving on to other things.
