Writing a Substack

Hi All,
So recently I've started writing a substack that's physical commods focused. 
Sort of a casual thing that I do on the side mostly because I'm bored and since I got rejected from all the finance clubs at my school, don't really have a way to like display "Passion for the Markets" whatever that bullshit means. 
I write once a week and usually like to write about stuff that interests me like shipping, uh fertilizer, coffee. Whatver floats my boat I guess. I don't really do a market recap like "S&P closed at 7000, here's my top 5 growth pics" Or like a DCF on Nutrien or something. I just like to tell stories about commods and what not. 
Good thing to keep doing? I've sent it to some guys I know at like Glencore, MSC, Cargill. They like it alright. I don't know if I should be a lot more techinical and what not but mostly I just be writing about stuff.
