The correct answer to this open question is the following.
Reagan's approach to criticism was different than President Trump’s in that President Reagan always respect the press and the different opinions of the people. The Media remembers Reagan as an honest person that did not like to lie and was precise with facts. Regan was consistent and never showed two faces. And people, rivals, and the media always respected that.
The actual US President could learn that from Ronald Reagan's legacy in order to have a better ore more decent relationship with the media and with those he considered his enemies. The actual President must learn to cope with different opinions and tolerate the ones who do not think like him. Being stubborn does not help his image and just gives more arguments to his rivals.
