Click on your avatar in the upper-right corner.
Go to your Channel.
Start making content and publishing it there.
That’s the easy part and it’s all free.
The real questions are…
What is your content about?
Is it interesting/fun/new?
Will people care about it?
Can you market it?
And on, and on.
Plus, you have to be consistent. Producing quality content weekly or more. There are also YT rules and algorithms to pay attention to. And, constant promotion across social media platforms.
Plus, nuts and bolts stuff like the right equipment and good storytelling skills.
Lastly, a ton of luck. Some stuff just hits because it hits. I’ve seen very talented artists producing regular content for barely anyone. Then, there’s a little kid who reviews toys and makes millions.
Either way, you gotta start with an idea and the desire to make regular content.
