The most effective leaders of companies in transition are the quiet, unassuming people whose inner wiring is such that the worst circumstances bring out their best. They're unflappable, they're ready to die if they have to. But you can trust that, when bad things are happening, they will become clearheaded and focused.

Greatest danger is not failure, but be successful and not know why.

Indeed, the real question is not, "Why greatness?" but "What work makes you feel compelled to try to create greatness?" if you have to ask the question, "Why should we try to make it great? Isn't success enough?" then you're probably int he wrong line of work.

Get the right people on the bus, the wrong people off the bus, and the right people in the right seats...

Bad decisions made with good intentions, are still bad decisions.

For no matter what we achieve, if we don't spend the vast majority of our time with people we love and respect, we cannot possibly have a great life. But if we spend the vast majority of our time with people we love and respect - people we really enjoy being on the bus with and who will never disappoint us - then we will almost certainly have a great life, no matter where the bus goes. The people we interviewed from the good-to-great companies clearly loved what they did, largely because they loved who they did it with.

True leadership has people who follow when they have the freedom not to.
