Traveling around the world it could be an awesome experience to tell your kids when you become older, how you went to europe and you ridded a elephant and how you learned a new language from africa. Traveling at your 20' maybe is an dream, but it has some contra because you need to get a lot of money and leave your family for a time and maybe it is a dangerous travel around some countries that has some guerrillas and problems you can get hurt in the time you travel.but there are more pros because you meet new friend and if you are shy you have the opportunity to make a tons of new friends.
also, you need to know the places where you will stay and explore, because getting in some place that you don't know and you don't understand the local language it could be a terrifying experience.
