Life is a group project where you still get graded individually.

You will spend most of your time depending on other people, and almost none of it sharing their outcomes. A team can carry you through a season and still leave you exactly where your own work put you. That cuts both ways. Being on a struggling team does not have to become your result either.

Do your piece to a standard you would sign your name to, separate from how the group is going. Then be useful to the others without waiting for a fair split. The part you control is your own record.
