Play As A Team But Don't Follow The Crowd
To be a good team member, you have to adapt and be willing to help the team succeed. Sometimes it means doing things which aren't your strengths, or even things you don't like to do. If there is a process in place everyone else follows it is important as a team to follow that process.
It is also important for you to remember you are a unique individual. You have different strengths and talents. You might have a different approach than others do. You see this a lot in sports where someone has an unusual stance or throwing style. Everything says it shouldn't work but it is effective for them. The same is true for you, you bring a unique view of things.
You also may see something that is a problem that others don't. Even if you follow the policy you know you are still going to have an issue. You need to be able to speak up, take a stand when something is not right.
It is one of many dichotomies in life. You need to be a good team mate, but you also need to be the best version of you there is. Sometimes that means adapting to the team. Sometimes that means standing up for a better way for the team to act. Life isn't as simple as one or the other. Unfortunately "it depends" is true far too often. We have to realize we need to be both.
