Answered by Adrian Ingram, e-book publisher & Youtuber
I would recommend starting up some sort of online business on the side, while you're still working a regular job. Once you've built that to a level where you're comfortable to live without going backwards, quit the job and head off on your travels!
There's so many different ways to make money online. Personally I publish Kindle books and haven't experimented with too much else. Right now I think that Amazon presents a lot of opportunities for building a solid income relatively fast. Whether you choose to publish Kindle books, sell physical products through Amazon FBA, or sell shirts through Amazon Merch, I think there is a lot of potential there.
