President Trump has yet to fully embrace the fact that he is no longer running for office. Therefore, the actions he takes are no longer about promoting himself over others and the comments he makes carry great weight. His advisors would do him a great service to sit him down, tell him the executive orders need to be minimized so that he  is not the daily story  and let the legislative branch operate. Press the reset button and quickly before more damage is done. 

They need to disable his Twitter account because Presidents do not conduct foreign policy with other heads of state via Twitter and they blurt out like bullies. They need to school him in manners and appearing presidential. No more thumbs up signals every time he signs a document- it's childish.

The key point is that the office of the presidency is above any one personality. If he continues to bring disrespect to it,  his will be a lonely world. Other foreign leaders will marginalize him ( yes the US can be marginalized).
