Dude, you are so much more handy than I am.
I don't think I ever shut down. I'm not saying that's a great thing necessarily, but for example today (Sunday) I hit the gym and then the beach... while at the beach, floating in the water, I was thinking about content + marketing strategies for my consulting business.
I think the closest I've been coming is that lately at the end of the night I'll eat a late dinner on the couch, and then sorta head to bed as I start to drift off. But most days I eat dinner at my desk
I think shutting down might look different for everyone. You are a beast though!!!!!! Hitting the gym.....maybe that's your version?
I hear you on the eating dinner at the desk. Sometimes I forget to eat and I lay in bed at 11pm and I start getting hungry. I hate when that happens haha!
