I don't believe in leadership styles. We certainly hear plenty from all sorts of business gurus that this style or that is ideal. I would argue, however, that talking about styles has little value because we are incapable of leading in a way that is inconsistent with who we are as people.
In today's business environment, where innovation, motivation and productivity are more needed than ever, this style of leadership is rapidly losing favor. Not for any "soft" reasons, but because it simply isn't effective at driving business growth.
