Travel broadens the mind, but often dilutes it in the process. There is more of a stretching than a broadening, with depth being sacrificed for more extensive shallows.
The classic traveller is like a salesman in that he has to compromise and bend to suit others, being dependent on their good will. The wise, however, do not compromise, and thus are not strangers to cold and hunger.
Therefore, if you haven't the strength to travel as do the wise, then settle yourself until you are. If you travel too soon your mind will become overrun with plans and concerns for food, shelter, and how to please others. Such a mind has no room for real thought. So, be careful how you run, for you may leave something valuable behind!
