Encouragement in song and verse.
This is a video popular in Pakistan. The singers in it are pop stars there and they got together to do this song. (This version has English subtitles.)
I've said before, national mythology, or self-identity is probably the most important determining factor there is for what people can do tomorrow.
And while I'm linking videos. Here's a very different one from a Marine. Blackfive has the words if you'd like to read them. (Or if the link to You Tube doesn't work.) A call to unity and service.
