The best thing you can do for yourself

New Zealand is honestly the most beautiful place with the kindest people I've ever encountered. No matter how big your expectations are of this place, they will always be surpassed and you will be floored by the majesty of the landscape and the variety of species that are unique to New Zealand. I would highly recommend seeing the Waitomo Glowworm Caves. The vast number of glow worms will make you feel so small under a blanket of a million blue stars.

If you have the chance and the means to volunteer abroad, New Zealand will not make you regret doing so. It's really the best thing you can do for yourself.
