Hello Cato-the-Elder! I searched the internet for "earning while traveling" and about 17 million results came up with many suggestions on how you can earn while on the go. I am sure you can search for those too. Here is one: https://expertvagabond.com/paid-to-travel-world/
On another note, you mentioned about giving up school for a year so you can travel. There is no harm in following your heart but I suppose you heard about the saying "live within your means." That is something to think about but again, you can go where your heart is.
Good luck!
Thank you!
