A Quote To Live By

I can't find the exact reference to this quote so if anyone can tell me where to find out if this is an actual quote from Sister Hinckley (which I believe it is but my seminary teacher background is demanding a legit reference), let me know. Whether it was said by her or not, it is a fantastic quote. One that should be read on a daily basis.

" I don't want to drive up to the pearly gates in a shiny sports car, wearing beautifully, tailored clothes, my hair perfectly coiffed, and with long perfectly manicured fingernails. I want to drive up in a station wagon that has mud on the wheels from taking the kids to scout camp. I want to be there with grass stains on my shoes from mowing sister Schenk's lawn. I want to be there with a smudge of peanut butter on my shirt from making sandwiches for a sick neighbor's children. I want to be there with a little dirt under my fingernails from helping to weed someones garden. I want to be there with children's sticky kisses on my cheeks and tears of a friend on my shoulder. I want the Lord to know I was really here and that I really lived." -Marjorie Hinckley
