You don't have to be a manager or a team leader to motivate others. Offering a listening ear or providing words of encouragement can make a world of difference to your coworkers. Sometimes, just being a positive influence and showing up consistently can also make a difference.
If you have worked in a leadership role, think of ways you helped set clear goals or helped individuals cultivate a new skill. Reflect on your experience and share some ways that you have helped encourage others to keep up the good work!
