Some people, like me, feel exhausted and empty after finishing all the trip and coming back home. It makes us have hard time to get back to reality from time to time. However, having a memory of traveling somewhere can be a great driving force to progress our life. For example, I have an experience of traveling North America for a month about 5 years ago. This memory still is a motive force which makes me keep moving my life and wish someday I will be able to visit there again.
