I am referring to the fact that the Presidency has been described as far more an exercise in patience, absorbing information and careful deliberation than say running a typical business especially a dynamic one like Trump used to. He is by all accounts a very smart guy. But by all accounts he isn't a particularly patient one.

I'm not disagreeing with you; I'm just asking you to cite one or more of these accounts describing his lack of intellectual stamina.

And we all saw through the 3 debates that Trump started off well and then really struggled towards the end e.g.

This account [1] by the ghostwriter who wrote 'Art of the deal', who spent months with him, suggests that he is neither smart nor patient. Over his long life, starting with a very silver spoon that he wasn't able to destroy, he effectively focussed most of his energy to coming up with a couple of heuristics for making deals and communication. I get the impression he spent most of his life's effort on something that might be called 'social hacking' here.
