@Germlat,
If they've traveled the world but it did nothing to change them, they really didn't see or do anything worthwhile.
Travel should:
1. be educational
2. meet interesting people
3. see the sites that are world famous, and learn why they are famous - a) UNICEF World Heritage Sites, b) cultural home to learn about your ancestors, c) learn about other countries and cultures
4. experience meeting different peoples around the world *I have friends in many countries including Africa, Germany, UK, Malaysia, Canada, Singapore, Bhutan, Italy, Moscow, Cuba, Mexico, Cambodia, Vietnam, China, and all over the US.
5. eat and drink different foods
6. study the country's history * I used to hate history in grade school. Now, I love it!
7. share your experiences with others. I started a travel blog four years ago, and I now have over 36,000 hits from around the world. It's taking me years to get rid of my photo albums that I've accumulated before I started my blog at travelpod.com.
8. have traveled to over 200 countries and 89 unique ones.
9. four trips planned for this year. seven trips in both 2013 and 2012.
10. I sincerely believe it keeps me in good health because of all the walking.
