Being able to work ~18 hours/day, every day will tend to put one inside of the OODA Loop of most mere mortals.
I don’t think he spends 18 hours a day. I think he uses people effectively and delegates by allowing people to deal with the details as he goes after the bigger picture. He trusts his people because he’s that good at reading/picking people and acts quickly when they head in the wrong direction.
In addition, he’s a man of action so the past ~3 months since the win he’s not been just congratulating himself and his team, he rolled up his sleeves and has been working that entire time putting together the paperwork. Now he just has to sign a paper and announce it. He likely has stuff ready for the next month in this manner. In the meantime he’s actually working on the next thing that will be signed once he thinks it’s ready for the 2nd month. I imagine things won’t slow down till May/June time frame when he takes a small break with his family.
I see him working 12 hour days right now, since his son headed back to NY for school. Of that about 4 is just having dinner with people and reading them to see where potential hurdles are going to come from for the big pushes he’ll need on Taxes/Tariffs. I see that likely as the 3rd wave in late March/April.
Remember the guy is 70. Energy or not, the body can only do so much and the last thing I want is to have him wear out before his term(s) are up. I think he gets a few power naps and a solid 8 every day. I also think he doesn’t stress over a lot of things. He makes up his mind, doesn’t second guess, and moves forward. He’ll make some mistakes, but just as in his business he’ll correct them quickly.
