Aries' famous temper can come out at the strangest times. Your competitive nature may have you bickering with friends over a seemingly friendly Scrabble game. And forget it if you're in a local sports team or league. You have to win at all costs! But do you, really?
If you want to keep your job, it's crucial to think of yourself as a member of a team... and as the cliché goes, there's no I in team.
This metaphor can play to an Aries' need to compete while still using their skills for the benefit of all involved. If you need to call out someone who is not pulling their share, Aries is already on it.
