Running a business alone means you're the CEO, the intern and the guy fixing the website at 2am wondering why a button disappeared and everyone in between.

I started GTG with zero business experience. Zero content experience. I didn't know what a funnel was. I thought "branding" meant picking a colour and calling it a day.
No one taught me how to edit videos, write emails, build a website, manage a community, handle contracts, do taxes, create content calendars, or deal with people who think "refund" is a personality trait. I just figured it out. Badly at first. Then less badly. Then somehow people started paying attention.
The truth nobody tells you about running a one man operation is that it's not glamorous. There's no team meeting because you ARE the team meeting. You're brainstorming with yourself in the shower and approving your own ideas because no one else is going to. But I wouldn't change it. Every single skill I have, I earned the hard way.
Still figuring it out as I look to scale, but that's the thing, I probably always will be.
