Working effectively with other people

The evidence that work effectively in a team is that I play football three times a week, therefore I'm more comfortable working in a team. I have played football for about 14 years this means i have been playing in teams and i find it relatively easy to work in groups.

Apart from football i have also done NCS which allowed me to take a leadership role as well as following and i was able to pick up new traits which helps me work better in a team.

However, i feel like i can improve more because i can be stubborn therefore by the end of two months i will be able to work more efficiently.
