California millionaires reveal their top tips for getting RICH - as they detail their own very unique money-making success stories

Southern California is known for it's expansive coastline, beach activities and, of course, the beautiful multimillion-dollar houses.

With the average house price in the Newport Beach area almost $3.1 million, according to Zillow, content creator Noah Kagan wanted to know about the people who own these mansions - and how they made their millions.

In a recent YouTube video, Noah, who is from Austin, Texas, went door-knocking in one of America's wealthiest zip codes to find out more about the homeowners and their humble abodes.

'The houses we're going to check out today are between $15 to $20 million,' Noah, who is a the founder of an app aimed at entrepreneurs called AppSumo.com, explained.

The first house he visited in Newport Beach in California belonged to a couple who made their money through strawberries, and now own several vineyards

'We're going to go knock on some doors and find out what do people do for a living and get advice for people like you and me,' he added.

After being rejected by one household and one Ring cam, Noah came across a woman who lived in the area with her husband, and shared their unusual path to how they secured their fortune - and their $12 million home.

'We were in the strawberry business,' she told Noah. 'And then we kind of fell into the wine business. We have several vineyards up north and so we had a kind of second career.'

The woman, who didn't disclose her age, then went on to explain how her husband fell into the field of strawberries.

'He had a strawberry project in high school where he planted strawberries [and] he had a stand,' she explained. 

'He started a processing business, so we not only had the fresh strawberries but then we processed them for freezer and for margarita drinks.'

She shared some wisdom for those wanting to build a business.

'Be an honest business person - always tell the truth, don't try and BS people,' she instructed.

'You know what is really important in life, it's you family, it's your faith,' she continued. 'Because those are your core values.'

'If you're successful,' she added. 'You gotta give back.'

The next home was worth $9 million according to Zillow, and belonged to an architect and physical therapist

The next house belonged to an architect who used to design company buildings and churches - but has since retired.

When Noah asked him about finding success, he reminded the content creator that it was all relative, and it's important not to just focus on yourself.

'[Being totally self-focused] is not a healthy existence and I think what you're doing for you doesn't matter at all,' he explained. 

'It needs to be something longer lasting and something of a bigger scope than just your reality.'

However he admitted his $9 million dollar house was completely funded by his career, explaining his wife is a physical therapist who owned rehab centers.

The next person to offer wisdom was also retired but had worked in commercial construction - building data centers for companies like Google and Facebook as well as hospitals.

The next home they approached was worth over $11 million, and belonged to a man who had worked in commercial construction

The man, who started out earning $21,000 a year when he first began working, ended up working for a company called Southland, saying they earned $50 million in revenue when it started, and by the time he had left they were at $2 billion.

He recommended working in an area that drives you, and something that fuels your passion.  

'If you don't have passion about what you're doing then you know you're why do it,' he quipped.

The last man Noah interviewed is a writer, who made his money from selling a children's book a decade ago - and has enjoyed the money from reprints ever since.

The creative, who lived in a $15 million home on the beach in Newport, gave his advice for those wanting to make their millions is to take one step at a time.

'People always come up to me and say: "I want to write a book, how do I get it published?'' he relayed.

'You write the book first you know, that just escapes people,' he said. 'I tell them just write the book first. Try that and then go from there.'
