I finished watching the leadership instruction tonight. I'm not sure why they call it leadership instruction. There is not very much instruction for leaders. There is a whole lot for individuals and families with a good portion stressing temple worship and some family history. The only real leadership information was in the related content that described the family history organization that should exist in each unit.
You can work at gathering Israel or you can just let it happen naturally by taking ancestral names to the temple as often as you can.
