Something many Boomers didn't like much were routines and joining.
"Keep your options open" -- moving around, moving on. Even if you stayed in the same town, you probably aren't in the same groups. You probably don't do the same thing every Tuesday.

Routine is hard....
Point of this decade is... making meaning.

More into new experiences, new sensations.
But there's usefulness and meaning in familiarity, in making the time to do the same thing.
