Being open for new experiences will mean that you will experience new things quicker.
Respect local habits, religion and learn about the past, present and future of the country you are in. Be open to try new food, from trying Springbok or Crocodile in Africa to bugs in Asia! Maybe you like it, maybe you do not. Atleast you know after you tried!
Try different things. Instead of always chilling at the beach, take a hike up the mountains! Experience a different side the country you visit has to offer, and come back with great stories to tell to your family and friends!
