Graham Cochrane with his wife and newborn daughter moved to Florida in 2009, when his work went down and lost the job. Cochrane thought that the book of Tim Ferriss - "The 4-Hour Workweek" that he read and bought, was way far from his reality, and concluded that every single one was useless.

The 32-year-old Graham Cochrane said: "I have never been entrepreneurial," "I was a scaredy cat. I wanted a stable job to pay my bills and not have debt."

As Graham Cochrane's savings were becoming less, he then went to the craft he'd been pursuing since his 20's - the freelance recording and sound mixing, and he even called it the passion-project-slash-side-job.

An extra $1,000-$2,000 that he brought in a month, appealed to Cochrane's mind, that he and his wife, a photographer, will use their savings to increase his freelancing and boost up his $50,000 annual income.

Then Graham Cochrane created a blog to cater answers to the consistent stream of emails he had been receiving. The emails came asking technical questions from friends and acquaintances.

Cochrane renamed the blog The Recording Revolution in January 2010, and he can't forget the first two years of it, that the blog made hardly any money at all.

After he made freelancing his primary focus for almost six years, his blog site is now earning between a stunning $35,000 and $75,000 a month.

Cochrane's blog always offers the free content, aside from that, the cost between $39 and $897, and a monthly membership of $27 for his added in-depth video courses on different aspects of sound mixing and recording. Cochrane estimated the courses were taken between 6,000 and 7,000 people

Cochrane said: "It's a weird phenomenon," and "Because I was a musician, I expected never to make any money."
