Actually I think you are right that is why he has been so successful. you see Polticians like order and calm waters, Trump on the other hand has worked in the real world he has had successes and failures, (More successes than failures) so the Storm of something might fail does not bother him, because if he does something and it does not work, he is not so invested (like a politician) to keep it going he will end it and try something different..
This is the problem with Government if it fails they think well we didn't throw enough money at it, instead of cutting losses and changing direction.
