How To Create A Substack
If you don't have a place to write publicly already, you can start a Substack. It’s free, it takes 5 minutes to set up, and I will explain how.
Next, Connect with Twitter or skip and make an account:

Then, set up your profile.
For the bio, write something that tells a little bit about your interests. Where are you working and what are your interests? What are the larger themes of your career?

Next, name your publication and say what it’s about.
The important part of your publication and writing online in general is that you can determine your niche and hone your interests.
You can always change this, so put a placeholder if you don’t want to decide now.

You can import a mailing list if you have some names and emails. This is critical to Substack. Don’t write without letting people know. Start small with your family and work from there.

Congrats, you’re set up and ready to get started.
Some quick points around navigating Substack.
First, the Dashboard button on the top right is key to getting around Substack.
Once you click Dashboard, you can see your posts, subscribers, stats, and settings.

Now, a critical point: add subscribers if you haven’t already (click Subscribers on the top right).

Take the next 15 minutes to add some low-risk people that you can start sending your material. Add your family and friends. This is essential to begin to get feedback on your next posts.
In the future, you can ask people you know if they’d be interested in subscribing to your newsletter to hear more about your thoughts on your career and interests.
Finally, create a new post.
Again, the best part of the internet and writing is that your writing can be distributed an infinite number of times with no additional effort or cost to you.
As such, taking the time to write one or two posts can yield benefits into the future. As always, start small and don’t worry about being perfect.
