What form of content would you like to create?
Written, audio, video, photos, memes, graphs, music, art?
Some easy ways (imho), though I would defer to someone with more experience that writes professionally, here’s my 2 cents after about 200 blog posts, 100 videos, 200 jams/songs (2021 & 2022) and 10 podcasts 
1. Set aside an hour or two and just start writing, talking, recording audio/video. The first 10-20 times will probably be a steeper learning curve, but that’s just part of the learning process.
Once you’ve created the draft, then go back and edit it – as opposed to editing a lot while creating.
(Also, keep in mind that once a person has written/etc about a subject doesn’t mean that can’t write about again in the future – it’s about building momentum)
Or you can create an outline for what you want to talk about.
For writing – you may want to brainstorm the top 5, 10, 20 questions/pain-points/themes/how-tos/listicles/reactions people have in your niche, for example.
I definitely can answer questions more naturally than just writing something – this might work for you too – think like someone asked you a question (sort of like how I am doing right now) and then create a response.
2. Go to places like Quora and answer the questions – also save your answers and use them as a blog post, podcast, video, etc. You can modify the answers and link the answer from the Quora to your longer answer on your blog, etc.
3. You can get people to create content for you, (like on UpWork), but then (in my experience) you become an editor/project manager as opposed to a writer, etc. It depends on a person’s style (prefer content creation vs editor/manager/etc) and the budget.
For me, it probably took as long to become a decent editor/manager (in a new technical subject public health) as it did to write the articles – it was definitely worth learning the editor skills, though it didn’t really produce more content than I could have on my own in the same time that I dedicated to learning to be an editor.
Big Blue Waves – this is/was my wellness website 🙂
It also depends on the person’s biz model and how they want to focus their time/money/energy and how important it is if the potential client’s need to relate to the person (for example Nomad Capitalist vs a company without a strongly visible spokesperson).
4. Another option to becoming an editor is create the content (word, audio, video, etc) and then send it to an editor who will then polish it up and publish it. This is what a lot of people do when creating videos.
5. This is more of a right-brain way of writing, but it also sounds like the writer (I like Steve Pavlina‘s style but it’s more woo-woo than a lot of people like) started out with the basic understanding on the left-brain skills to write good content, etc (https://stevepavlina.com/blog/2010/12/how-i-write/).
Also Zen Habits (https://zenhabits.net/writing/) – imho you probably just interchange writing with another style of creation and use a similar process.
Best wishes!
