I have a quote to share from the Ensign (May 2009) President Eyring said in Priesthood Session:

"You will show by your face and manner that you care for the people. They will see that your love for them and the Lord makes you unafraid. And you will be bold enough to bear your testimony to truth. Your humble, simple and perhaps brief testimony may touch the heart of a person more easily that your more experienced companion."

He was talking about home teaching and fulfilling priesthood responsibilities but I think that this applies to all of us who wish to serve the Lord and help to lift our fellow brothers and sisters. Maybe even in our own families.
