Definitely as a millennial I'm of the last generation that will remember arranging to meet up somewhere in advance and sticking to that plan (or rearranging over landline with more than a day's notice...)
But something I've noticed when I ask people in my team what their dream jobs are the younger people tend to say 'run their own businesses', 'work for themselves' etc. Whereas in our generation (in my circles anyway) that definitely wasn't so prominent. Maybe a side effect of seeing influencers making it big?
I mean yeah, I've been unemployed for a significant part of my working life. I guess you can also add to my list being the last generation encouraged to get a degree by well meaning parents and teachers at school 'because it will guarantee you getting a job for life'.
