How does one talk about their personal strengths without sounding boastful?

One of my strengths is that I am a team player. As I said in my introduction I learned the value of

teamwork while running Track and Field in high school. This attribute helped establish other

strengths such as being a better listener, being open to other people’s ideas and leadership skills. Another

strength is that I am willing to accept other people’s help and know when I am wrong. I once

heard from a high school counselor that a wise man is not man that knows everything but one

that is willing to accept when they are wrong. Healthcare is an ever evolving field, new

discoveries are made everyday. I am able to understand what areas I need  further

teaching on so I could become well versed in that arena. I do not know many things but I am

willing and able to find the right person who does.
