Achieving extraordinary things requires sacrificing work-life balance, says this 29-year-old millionaire.

Selling his influencer marketing firm for an eight-figure sum at the age of 27 made Timothy Armoo a multi-millionaire, but he believes that achieving greatness is not an effortless task.

Fanbytes' co-founder and former CEO, Armoo, grew up in a public housing development in an impoverished area of south London. He attributes his success to sacrifices, including giving up on what he believed was a healthy work-life balance.

Armoo stated in an interview with CNBC Make It that while he believes in working extremely hard, he absolutely disagrees with the concept of work-life balance.

"Significant achievements are not attained through balance; it's a myth."

Armoo stated that "there is a season for everything," which he explained as time periods when one must work extremely hard. He added that these periods may appear differently for different individuals and could last for three months, three years, or even ten years.

"During a specific time, you express the desire to achieve unique outcomes and differ from others. To accomplish these exceptional results, you must perform actions that are not typical," he stated.

Putting in extra effort increases your chances of success.

'Seasons'

Armoo emphasized the importance of having "seasons" in life, suggesting that one should focus on work during the hustle season and prioritize family, health, and personal life during other seasons.

"When you're in your family season, you should not focus on work-life balance. Instead, you should be intensely focused on creating the best family possible," he said.

At the age of 14, Armoo launched his first business, a tutoring company that linked students in need with skilled tutors, earning a commission on the fees.

At 17 years old, he sold his second company, Entrepreneur Express, an online blog, for £110,000 (around $145,000).

Like Bill Gates and Warren Buffett, he has devoted a significant part of his life to growing his business.

Bill Gates, the Microsoft co-founder, advised people to take breaks in their 60s, unlike in their 20s when he didn't believe in vacations and weekends.

On Saturdays, Buffett, the 94-year-old chairman and CEO of Berkshire Hathaway, continues to work six days a week at the office.
