Primary President

Just in case people want to know a little about what is new in our lives, I just got called to be the Primary President in our ward.  I'm not exactly sure how to feel about this calling but I'm excited about it.  I'm a little nervous because they only called one of my counselors this Sunday.  But when I talked to them they said that they should call people next Sunday which would be super nice.  I don't really know what to expect from this calling but in time I'm sure the Lord will show me how it all works.  If anyone has any specific advice or things that worked well for them in Primary let me know, I'm up for any input I can get at this point.
