There are entire subreddits dedicated to producing content.
Beyond that: to make good food, eat good food. Spend time watching N hours of tech YouTube and take notes on which you liked and which you didn’t. For the ones you liked make notes of why and try to replicate that (tone, storytelling technique etc.) and for the ones you liked less, find things to avoid or do less of.
What are your favorite subreddits in this area? I feel foolish saying this, but I had not even considered that there would be a sub devoted to this.
