Firstly, I have to say that I have never been go to aboad lol ,but I think the good points of travelling in efferent countries might be like these.
Travelling in various countries makes the traveler experience with the new thing, new culture, new way of life , new belief and etcs. The traveler can learn good things from each counties to adapt in his life. You will make friend with new people to share or exchange the knowledge of each country. Each country also has its tourist attractive places to visit so the traveler can take a photo.
However, the benefits you will get while travelling in abroad individually depend on what you are doing or looking for.
