traveling broadens our range of knowledge. not only that we could learn so much about different cultures and practices but also we could use the oppurtunity to relax ourselves. it would also be a good chance to train ourselves. traveling requires us to communicate with people that might be so much different with what we are. there could be great language and cultural barriers. the food would also be a big challenge for us, since it's a basic need that we couldn't avoid. our ability to adapt the environment would be well tested everytime we travel.
on the other hand, traveling usually costs time and money. it would be much better to travel not only when we possess enough money and time but also health. traveling are often tiring. we should make sure that we're in the proper health condition. and as mentioned before, money is an important aspect. unexpectable things often happen, and it would be somewhat easier when we have money for the unexpected.
