Missionary Work, and Acting in a Godly Manner

How can missionaries today teach and act in a godly manner? I know that just by keeping the standards of the church and the mission standards can help increase the spirit so much for missionaries. Even as church members we are missionaries every day, and if all of us keep the standards and set a good example for our peers, we can have much better missionary experiences in our lives. I know one thing I personally could do to increase my faith and missionary work is to continue to dress modestly. To respect my body and to show others around me that I have respect for myself makes teaching the gospel to others a much more smooth and wonderful experience.
