Confidence is not lodged in people's brains, it comes from the support system that surrounds them. Let's not confuse confidence overall with just self-confidence. Self-confidence is only one part of confidence. People also need confidence in others - their colleagues and leaders - that they can count on them to do the right thing and not to let them down.
Rosabeth Moss KanterThe degree to which the opportunity to use power effectively is granted to or withheld from individuals is one operative difference between those companies which stagnate and those which innovate.
Rosabeth Moss KanterCompetition has never been more threatening than it is now. Innovative thinkers challenge the status quo in their organizations. They are often viewed as "troublemakers." They threaten the defenders of the status quo. So competition within an organization can also be brutal. The most effective leaders overcome "the ideology of comfort and the tyranny of custom" by being change agents themselves. They encourage and reward innovative thinking. I have observed that people only resist changes imposed on them by other people.
