Your gifts and strengths are yours and only you know them well. No one else can define them but you.
People come in different shapes and sizes with different paradigms. Do not let others define who you are. They only define themselves.
You do not need to show off. What you need is to have a powerful self-concept and self-image. That will reflect in your demeanour, in your deeds and in your actions. You do not need the approval of others.
