Thanks for the question. Although Showing Up stays away from political opinion, I would say this about your question:
Donald Trump was not given a chance in a million to make it all the way to the White House. In fact, he was laughed at for even trying. You may want to read that last sentence one more time.
It doesn't matter how serious others take your dreams; it matters only how serious you take them. You can't do everything, but you can do anything.
