>without taking the time to do it right" is more reflective of his belief that whatever he tries [even just being president] will be fought, so his options [from his POV] are "do it now" or "don't do it at all", not "do it right"
This seems completely wrong and ascribes motivations to Trump he clearly doesn't have. I think his framing is much more "everything I do is correct therefore this will work." Everything he does makes sense when framed that way.
Yeah, I think there's plenty of evidence to contradicts the theory that Trump is somehow "now or never" decisive.
For example, his habit of promising all sorts of things in "two weeks" and then doing nothing. [0] Neither "now", nor "never", but always "soon".
Or look at the stream of inconsistency from the White House about quantum-mechanical tariffs, as they endlessly mutated between: On, off, on but only when being observed, paused, never paused that was fake news, on but a different set of tariffs, off because a fabulous deal was made but don't ask about the details because you wouldn't know that country anyway, etc.
