2468"So probably 10 years ago I met a guy called Rob who was instantly fascinating to me," says Louis in his audio commentary.
"He had gone a very radical route to most people in society. He'd left his job, he'd given away everything he owned.
"It was just so different to society and it really challenged me. It made me question everything I'd been taught about society and what we should and shouldn't do.
"One day he just looked at me and asked me this. It sounds like such a simple phrase and sounds like something you could easily answer but it's a very deep question.
"What do you want to do with your life? Are you doing what you want right this moment?
"It set off a series of questions which led to my whole life changing direction, because I wasn't doing any longer what other people wanted me to do, or what I should be doing.
"It was deep down, in my heart, what I want to be doing."
Louis has a very successful YouTube channel in which he posts a daily video chronicling his various adventures.
