This is an interesting topic, but it's easy for you to write if you really have travel experience as well as a passion for travel. If so, you can bring in your own experiences into this essay. However, these are a few points for you to expand on;
1. How your experience broadened your perspectives
2. How it helped you to transform into a different personality ...for example, if you have been a very shy person, how this experience helped you to come out of your shell
3. How it helped you to be more confident
4.How it changed your perception about other people
