I spend 3 months in Australia and New Zealand. And travelled around a lot in other places too. My answer to your question would be learning about different countries, different cultures. Seeing that there are interesting and friendly people everywhere. I feel like it made me a lot more tolerant and open minded.

If life ever gets really though, I know I can always go to NZ. Sounds silly, but I _think_ this has made me more resilient, more able to put things into perspective.
