"My first blog I got paid for made €80, and thought it was amazing. Then I started to make around €5,000-€6,000 a month, and it started snowballing from there."
"If I can do it, anyone can do it".
So how exactly did Johnny generate so much cash from his travels? Here, he shares his tips with Independent.ie.
How can I start making money while I travel?
"The Internet. The idea most people have when travelling is to save up enough money to travel for a certain length of time."
"In fact, working while you travel is the key. It's a change of mindset."
As you travel, for example, you can sell stuff online or teach English on Skype, Johnny says (he even traded currencies). The key is to generate money as you go, he says, rather than saving like mad beforehand. "The mindset needs to change."
"99.9pc of people don't get paid to travel," Johnny says.
"You travel to create the content and once you have the content you can create the blog/videos to then sell to places that would be interested. That then generates money to your blog."
He recommends starting a blog on places you travel, keeping note of all that you are doing. For this, you will need a domain name and web hosting - he recommends buying your own domain and paying someone to build the site, as it will stand out more.
Standing out, of course, makes it easier to sell ads.
"Once you start building your profile then it becomes easier to sell. But unless you're a big name on social media etc, you won't get paid to travel," he adds.
Johnny had to blog constantly for a year before he was approached for content. Lots of people post content for a few months and then get discouraged, he says. But one of the keys is sticking with it, and building up that content base.
"You need a lot of followers really to get people to notice you that way."
What's your favourite place in Ireland?
I spent two weeks road tripping in Ireland last year and it really is a beautiful country. I loved Inis Mór in the Aran Islands, and Slieve league in Donegal. The Cliffs of Moher are stunning, and I saw the Dark Hedges (in Northern Ireland) for the first time as well.
