People, unlike mules, have the ability to learn new things that they have no natural talent for. Many "dreamers", as you put it, do fail in their initial goal of "going around the world" thanks in no small part to your enthusiastic reinforcement. As a leader, one has to enable those in his charge, provide positive feedback and as best they can see their goals as they do. As a member here you should be considerate to everyone, even those people who dare to dream. Your comments were not directed at anyone in particular but they do strike me as asinine.
I hope I never meet you on the water after I spend thousands of hours learning what I need to know to attain my goal only to have you dismantle my dreams because I dared to dream.
You're damn right you hope you never meet me. I have little tolerance for righteous fools.
