Hey Cadence, that’s an awesome ambition and the world truly needs more people like you. Teaching English is a common way to see the world and help natives of the area where you end up residing. There are also ways to help people through the Red Cross and other international volunteering vocations. I personally have a friend that joined the peace corps to teach English to children in Ghana. If you are looking for a way to make money internationally, teaching English would be a great option. If you are still wanting to stay near home, there are companies that have their employees use webcams to teach internationally.
Also so I would look into government positions overseas to help others. There are a lot of opportunities but you’ll have to do a bit of research. I hope this helps!
