It's bad to be narcissistic.
A project led by Peter recently won in a competition.
Peter wants people to admire his success.
Peter talks a lot about how the project was a group effort and how he was lucky to lead such a great team, which won that great award.
Peter keeps on telling everyone how the project won because of how brilliant his own ideas were.
People who worked on the project with Peter feel empowered and valued.
People who worked on the project feel ignored.
