Selling oneself short

Yesterday in a meeting with my boss and three other people we were reviewing my resume and my profile on an employment search engine. All four of the other people involved in the meeting told me that I was selling myself short. Each of them told me that I need to redo my resume and profile. I grumbled about it, but ultimately redid my resume. I am so excited about the new one. I sound AMAZING now. I would want to hire me. I am so excited to show them the newer markedly better version of myself.
