Funny, for me it's terrifying (which turns out to be a fake emotion) and then it turns into joy! I always try to have gospel tracts on me (one is a "gift for you" with a $2 bill in it and the other is a 10 commandment coin).
Lately, I've just been trying to reach out to strangers and ask if they can name all 10 commandments. It becomes pretty interesting! Not many people know them all, and it seems most people in the church don't know them, either.
