Documenting vs teaching is how I decided to try my hand at writing again, currently writing something about brushing up on HTTP. Problem is technical writing is so slow/researchy!
Thinking of writing as slow and researchy indicates to me you're still seeing it as teaching. Tell your story.
Exactly Jacob, it's a bit of a mindset change but it is really worth it. No one expects an expert, just tell us your impressions and journey.
