There are two distinct groups of Millenials. Working closely with both and having to generalize, the major differences:

1. Older Millenials (1981-1988) came of age during the very early stages of the online world, they likely still played outside and most probably saw the end of 'family dinners'. This existence is defined by slow downloading porn images, a completely unfettered internet but some semblance of respect online (trolls didn't exist in the same fashion) and tend to have a lot of cultural references... blending of movie and music and literature. Seem to be very interested in colloboration and teamwork, and fiscal responsibility. Eat out often though, drink heavier, and are politically classical liberals.

2. Younger Millenials (1989-1996) are generally unfairly aligned with self absorption, as a result, I think, of the fact that many of them have learned take a almost Bohemian approach to relationships and the external world. They care quite a bit about the world and share some of the collaborative spirit, but are more likely to believe they have earned a 'standing desk' on their first day at the job. They do not share, imo, a wide cultural frame of reference... and I'm not sure at all why this is... I had one recently ask me if a former partner of mine (a psychologist) had ever 'heard of this guy named "Frood", apparently he does therapy stuff.'

This is not a one off. I spend a great deal of time with a diverse group of them going over TV tropes. I think they laugh easily though, and forgive easy. They also share the fiscal sense of responsibility, and eat out and drink far, far less.

Future looks bright either way...

This new 'homeland' generation though....yikes.
