Traveling is one of the greatest things a person can do for themselves, in my humble opinion. A trip to lands yet unknown? Oh the foods to eat, the sights to see! Travel enriches the soul and broadens the mind. It awakens ideas and understanding in people that heretofore had lain dormant.
It can also get prohibitively expensive. Especially for low earners out there (like myself) or people who may have special circumstances attached to their journey.
