1.I think leader of a team project at school is the first step to manage everything before you grow up.You must have responsibility,positive thinking,and solve problems. And I think if leader of a team at work you should have more responbility and takecare with another people for work like a family.
2.For me a better leader is someone who asks others to share in the decision making process. Because I think everyone should share in the decision making process if you make decisions and assigns duties that can make someone feels unsatisfactory, and works don't have quality.
