Traveling Abroad.

Have you ever made a decision in your life and felt like you needed it at that very second?
Well, I just made a very exciting decision for myself... I am going to enroll in an exchange program once my temporary position is up!
Although-I can't decide where I want to go.

Should I volunteer in New Zealand or Costa Rica helping out either animals, children or the environment? (Price approx. $1,500)*
...or should I learn a language in Paris or Italy (price almost $3000...ouch.)*
OR should I independently live with a wealthy British family in the United Kingdom learning about culture and castles? (Price just a little over $1000)*

This is definitely something that I want to do, I feel like it could be an amazing experience for an affordable price.
*Each price doesn't include tourism activities and airfare.

This is an opportunity that I am really excited about but I just need to learn to handle my money better so I can save and actually do this.
So if you know that I'm about to spend my money on something silly, please advise me against it and remind me of my potential travels in the New Year.

KThx.
