What better way to live life than to live as if you are part of a team all the time. This way you are not being selfish right but putting others before yourself. This is an esoteric responsibility that’s missing from our culture. When you do so you are are acting ethically you are asking oneself how do I treat others, right? How do I fit a team? What id your part? That is a positive step so don’t stop ask those questions it is a great step!
