I had a boss like this. Not sleeping at the office but had to put in 14-16 hour days and let everyone know that he did. Took me about a month to realize how inefficient and slow with every project he was. He easily could have had all his work done in a normal day and met his deadlines.Maybe that's how he got to be one of the best?
These folks aren't built like the rest of us. Saw one of the top investment dudes with a bed in his office. The drive these people have in their chosen field is unreal and doesn't make sense to a lot of us.
I'm driven to retire before AI and robots **** everything up. That's about it from a professional level now.
It’s all bluster imo
