This one is a bit long at 15 minutes and it's not directly related to the Military but IMO it's well worth the watch.
Essentially it breaks down this guy's opinions of why the Millennial generation is so depressed and the challenges poised by the addictive nature of social media as well as a failure to be prepared for life in the real world.
Applicable to today's military leadership as they need to be able to understand to effectively lead younger service members.
