The largest enemy of change and leadership isn't a "no." It's a "not yet." "Not yet" is the safest, easiest way to forestall change. "Not yet" gives the status quo a chance to regroup and put off the inevitable for just a little while longer.
Change almost never fails because it's too early. It almost always fails because it's too late.
The tactics of leadership are easy. The art is the difficult part.
Hope without a strategy doesn't generate leadership. Leadership comes when your hope and your optimism are matched with a concrete vision of the future and a way to get there. People won't follow you if they don't believe you can get to where you say you're going.
You don't have to be in charge or powerful or pretty or connected to be a leader. You do have to be committed.
People want to be sure you heard what they said; they're less focused on whether or not you do what they said.
If your organization requires success before commitment, it will never have either.
Part of leadership (a big part of it, actually) is the ability to stick with the dream for a long time – long enough that the critics realize that you're going to get there one way or another....so they follow.
