4. Spread good vibes

Optimism is contagious. Having an upbeat attitude can inspire everyone around us. A survey conducted by Gallup found that only 35 percent of U.S. managers are engaged in their jobs. This lack of engagement and its impact on employees costs the U.S. an estimated $77 billion to $96 billion each year.

Attitude is everything. Optimistic leaders can help motivate and engage their employees. A positive team will be driven to accomplish goals and work together to move things forward.
