The best way to motivate your teammates is to be a leader. Leadership is defined in many ways, and there is no one perfect way to do it. To be a good leader, you have to figure out the type of person each of your teammate is. Some teammates require you to push them hard, while others need a softer approach. The only way to find this out is through trial and error. You won’t know what works until you try it. The worst thing you can do is be passive, allow bad things to happen, and not speak up.
