One other thought to drill deeper into regarding lingering.
I'm the type of guy that always moves with purpose. When I'm done doing something, I'm quick to leave. Looking back on my life so far, I think this has often been mistaken as antisocial.
Every event involving humans is default social. Leaving quickly precludes much of life's social whimsy.
I'm much the same. It's hard to notice. Coming up having onsites with three and four and five consulting clients in a "normally busy" day (you want 'high touch?' I started before smartphones!) taught me to associate just that purposeful attitude with the satisfying knowledge that I probably wouldn't end the day running further behind when I started.
It's a good energy to bring to work or to a crisis. Everywhere else? Maybe not so much. I appreciate you mentioning it here; it can serve me also, as a reminder to work on that.
