He was not lazy.
It’s just that he found no point in doing things. Not that he couldn't do them, but what was the point? And he could do lots of things, great things - program computers, bond with people, build buildings, plan, strategise, think, do, walk, talk. Lots of things. But he found no point in doing these things, and for very valid reasons.
He could reach far and wide with thought, and foresee the realisation of each action.
In his view, the end would ultimately culminate in what would be its pointless beginning - ‘Start One’, as he put it. There is one beginning that ends where it began, so why do it? He was not lazy, he was a great man,
that didn't do much.
