From Jdowns thread in Colombia:
interesting observation. I forget how Einstein supposedly worded it, but great ideas will be met with violent opposition from mediocre minds. I see it all the time. And look at the condition of our country. It beats us into submission so we hold back our ideas. Part of it is ignorance and part is selfishness/envy. They don't want to share us and they don't want us having any fun they aren't having. Our inactions may be due to a fear of alienating the people we care about, and to that of the unknown. But the fear of the unknown is also where we get a lot of the adrenaline rushes pleasantly associated with travel.
