Travel and change of place impart new vigor to the mind.
~ Seneca.

The world is a book, and those who do not travel read only a page.
~ Saint Augustine.

Once a year, go to some place you've never been to before; you do not need to go far away, there are many hidden treasures around the corner from where you live as well.

Respect the environment, the people and cultures of the countries you are visiting. Especially show good example of not littering, recycling, etc. to the people who have not been fortunate to have the education to understand it yet.
