Know that we humans do not have to be stuck in our ways. We choose to do so.
When some people hear about an education different than the one they received, it is easy to shrug and dismiss. After all, new ideas, whether they are good or bad, look the same in their infancy, and the more different these ideas appear, regardless of their quality, the easier they are to simply right off as being unrealistic and Utopian.
It's a hell-of-a lot safer to dismiss these ideas than propose them.
It's infinitely easier to cite the "real world" as a place that simply won't tolerate such ideas.
It's convenient to perpetuate what everyone else perpetuates.
"That was nice... now back to the real world." More apathetic words have never been spoken...
If we all resigned ourselves to the safe, the easy and the convenient and decided to take up permanent residence in the "real world", how would we ever aspire to anything more than what we have now?
Focus too much on the 'now' and you'll be sure never to arrive any where else.
