^Agree.
And it becomes easier to do good work when you’re in a relaxed frame of mind that is free from the stress of competition. That way, your work is more likely to be free of errors…which makes your look professional. On top of that, your relaxed attitude will make you a much more pleasant person to be around…which is ALSO part of being a professional. Professional work and attitude are important. An uber competitive person will either have only one of these qualities…and can risk losing both.
