I worked with a workaholic in one of my professional organizations. He could be quite charming which is one of the reasons we hired him in the first place, but he thrived on situations of crisis, and if there wasn't one, he would invent one. Within minutes of entering the office he had every staff member fully occupied with his priorities  to the detriment of everything else. He was paranoid and defensive to any criticism or offers of help. Not a single staff member could work with him. He was always "right" and bullied staff members until they were in tears. We had to let him go. 

That is how this will end. Trump will be impeached when he has created enough havoc around him that his vice president and congress realize he is a risk to the country. Meanwhile the way to deal with him is by not dealing with him.  We should be talking instead to the powerful people around him, constantly pointing out his mistakes and reinforcing that in the eyes of the world he is not fit to govern.
