So good bro! I say write what you want to read about. I get caught up in the battle between staying in “my lane” and also producing something of value. If you know what you create adds value and not noise, and it brings you joy, then that is the article you should write.
Besides, the topic is just the vehicle for the refinement of your own voice. Find your voice, and the topics will become less important because YOU are the writer. Unless you go into technical manual writing, your voice needs to shine through the work.
And vulnerability in your work, like above, always helps. You’re doing a great job!
