One of the worst mistakes is to do nothing.

Leadership (according to John Sculley) revolves around vision, ideas, direction, and has more to do with inspiring people as to direction and goals than with day-to-day implementation. A leader must be able to leverage more than his own capabilities. He must be capable of inspiring other people to do things without actually sitting on top of them with a checklist.

The failure to find the right niche for people - or to let them find their own perfect niches - is a major reason that so many workplaces are mediocre, even toxic, in spite of the presence of talent. Leaders of great groups give them whatever they need and free them from everything else.

People vary enormously in how they learn. Some learn through their eyes - by reading but also by responding to all kinds of visual information. Others learn mostly through their ears or touch or other senses.

What makes a good follower? The single most important characteristic may well be a willingness to tell the truth. In a world of growing complexity leaders are increasingly dependent on their subordinates for good information, whether the leaders want to hear it or not. Followers who tell the truth and leaders who listen to it are an unbeatable combination.

Leaders know the importance of having someone in their lives who will unfailingly and fearlessly tell them the truth.

Failing organizations are usually over-managed and under-led.
