Here's why humility and active listening skills are key to effective leadership. Behind every great leader is a great team. The continued success of that team and its ability to thrive, however, also depends on the manager's ability and willingness to hear their employees out about the challenges they may be facing in the trenches or new ideas they want to bring to the table. Developing an ego or coming across, more often than not, as a "know-it-all" in one-on-ones or team meetings may be a tell-tale sign that you have a superiority complex, which can ultimately lead your team to failure. The good news is that once you're able to identify your own behavior patterns and recognize you're not the only voice in the room, you'll be able to nip it in the bud quickly and effectively—once and for all. Here, 13 experts from Fast Company Executive Board share how and why it's so important for leaders to avoid a superiority complex no matter where they work.
