"As I quickly discovered, nobody automatically believes in your dream. Nobody! You have to turn it into reality through your own sheer grit, bullheadedness and persistence."
This is a definite. I am sure that you've probably seen this situation in movies. Well, its when you tell someone your dream career and they laugh at you. Which would definitely pull your confidence down eyh. Yes, it often happens. Just to everyone. Only because everyone can dream. And they might have aimed a little higher. But believe me, nothing is impossible. Champagne dreams will only materialize if you really do the work. (;
