One Business Focus or Several in the first few years of entrepreneurship?

“One product, one avatar, one channel. If you have multiple businesses and you’re under 7 figures a year...STOP. More businesses clearly aren’t making you more money.” - Alex Hormozi

This line during Alex Hormozi’s YouTube video, “30 Minutes of sales training that will explode your business in 2022”, hit me like a ton of bricks in a super pivotal time in my business.

Us entrepreneurs and investors have shiny object syndrome a lot of the time. FOCUS.

But, from what I’ve seen, most heavy hitters in the business and investing world focus on ONE THING until they crush it.
Then, with their earned time, money, and knowledge -> they explore other businesses/investments.
But, it all starts with that ONE THING.

What do you guys think of this? 

Are you just focusing on one business starting out or are you growing several at the same time?
