There’s nothing wrong with a little healthy competition. When that competition begins overshadow what you’re competing for, it can become a problem. Take a moment to pause and reflect about what you’re trying to accomplish and who you might be hurting in your efforts to seem like the winner. Aren’t these people your friends, or at least cordial strangers? Are they taking this as seriously as you are? Make sure you aren’t looking like a brat in your efforts to look like the champ.
If it’s someone else who seems too competitive, simply compliment them and they should chill out a bit. Eventually they’ll see how silly they’re being and you’ll likely be there to witness and have a little chuckle.
