Encourage those on your team (or yourself at times) to go directly to the source of the frustration. Have you noticed that people almost always vent to the wrong crowd? They vent to individuals who cannot do anything to remedy the complaint; they go to work and complain about their spouse, or they go home and complain to their spouse about the people at work. When it comes to actually creating change and progress in life, it requires being courageous with complaining.
