I re-post this because I think it is terrific advice. But also because I have been there. I have been the overwhelmed leader, and been subject to leaders who took the hard way and ultimately wasted everyone's time. Leader development is the most important thing, and it is important to do it right.
Start small. Like many things, starting small allows the ball to start rolling. Before long you might find you have to hang on just to keep up. Leader development training is something troops should look forward to and never suffered through, but too often it is the reverse.
