"The limits of your world are bordered on all sides by your facility with language."

You are able to do anything you put your mind on. There's no limit, unless what is stopping you is your language. Your desire may be to travel but each time you travel to the same place, it will always be different. You aren't going to experience the same thing more than once. Go to a different country and you will feel like a new born opening its eyes for the very first time. It all depends on how you take things. Not speaking the language of that country will limit you from knowing different things, as well as socializing with others. Its like being in a box, you have no way out, no holes to breathe from, nothing whatsoever. But the only way you are able to find your way out is by following instructions on how to get out of the box. There's a limit to everything in life only if you don't look beyond your measure.
