Do you really believe that? Trump seems to me like a workaholic. He sure isn’t lazy. He enjoys challenges, and the chance to be the CEO of the biggest “company” in the world, the United States Government has got to appeal to a guy like Trump.
Yah if we think about it he's reached the pinnacle of success in his field. No more challenges for him really. But being President and accomplishing the goal of making the country great again...well...that sounds plausible.
And he's not one that the goal is to "be President."
