What should you do before 30 ?

I love travelling so i want to travel as much as i can(/as possble). I want to learn the culture of another country, meet foreign people, (and) try the special food of each country. The country I want to visit most is America. Because it's a large and modern country. It has 50 states, each state might be as big as my country. I love fitness(/I am passionate about fitness), so I train everyday. I want to train in a gym in America(/American gym), the ones I've seen on TV are very big and modern. In Vietnam, most gyms are not big and don't have enough equipment. I feel very excited when i see the gyms in America so i hope i can train in there one time. I love food, delicious food always makes me feel so excited, I heard that food in America is very cheap and tasty, I don't know if it is correct. That's what I want to do before turning 30. What about you ?
