He’s just a high energy guy. His normal routine is just a few hours sleep, up before dawn, reading newspapers, keeping informed, etc etc. He’s a dynamo.
I went to college with a guy like that. He’d do fraternity and student body politics all evening. Then study (engineering) till the middle of the night. 4 hours sleep and off to class. And repeat. Became a 7 figure exec.
It’s a unique talent for sure.
