In every workplace, there are three basic kinds of people: givers, takers and matchers. Organizational psychologist Adam Grant breaks down these personalities and offers simple strategies to promote a culture of generosity and keep self-serving employees from taking more than their share.

This week's video comes from Brené Brown and her brave and honest book for leaders – Dare to Lead. The book has the subtitle ‘Brave Work. Tough Conversations. Whole Hearts’ and is, in its essence, an attempt to redefine good leadership. Brene Brown firmly believes that genuinely great leadership is not defined by status, power, or titles but by something else entirely. According to her, great leaders recognize potential, take responsibility, and are vulnerable, honest, and courageous. Great leaders do not pretend to have all the answers, and they never let their egos get the better of them.
