Brothers Alex and Brett Harris wrote DO Hard Things for the teenage audience to encourage them to rise about society's view of them and allow God to use them to do hard things for Him. This is a book that I haven't read yet but it's sitting on my shelf. The title caught my eye when I first saw it and I knew it was something I wanted to read. Though I'm past the 13-19 age range, I have no doubt that I'll benefit from it as well.
