One of the unforgivable things that my grandfather did to Donald... he severely restricted the range of human emotion that was accessible to him. ...… - Mary L. Trump

My grandfather was an adherent to Norman Vincent Peale's doctrine of positive thinking. ...It allowed room for nothing else, and there are times in our lives when we are legitimately distressed... sad... in pain. ...[T]o be prevented to feel those feelings honestly and openly is a form of torture.

Donald... had to sacrifice whatever goodness there may have been in him once, whatever capacities of experiencing the full range of human emotions, to my grandfather... at the cost of all of us.

Donald learned that you could never admit you're wrong. That was considered a weakness and we've seen that, starkly, with the Covid 19 situation. He didn't do anything right away, and then when it was almost past time to do the right thing that would have meant admitting that he hadn't done the right thing in the first place. ...[T]hat wasn't going to happen, so the situation got worse and worse... [C]losely related to that was this idea of the power of positive thinking, which my grandfather really bought into... [E]ssentially, he took it to such an extreme that it became a kind of toxic positivity.
