This is an excellent message by Andy Stanley from Northpoint Church

"Left to themselves, virtually every person and organization is in a subconscious pursuit of the status quo."

"Unfortunately, your zeal for improvement isn't always appreciated out in the real world. As a matter of fact, your natural bent for leadership sets you up for resistance from virtually all sides–including other leaders.
And unless you understand the nature of these dynamics, the very instincts that qualify you for greatness can also lead you to disqualify yourself and sabotage your opportunities. Effective leadership means learning to challenge the process without challenging the organization. There's a fine line between the two. But it's a crucial line. "

"As leaders, we must keep a sense of diplomacy without shrinking from our scrutinizing nature. When you stop challenging the process, you cease to be a leader and you become a manager. "
