At least you didn't have a full coffee in the other hand.

Wait, 50 rejections since January? That's only like... what, 10 or 11 months? That's a rejection every week or so. I can't imagine keeping track of that many nos without going a little crazy. I just delete the emails and try to forget about them honestly, it's easier on my mental health that way. But dang, 50 submissions in that timeframe is impressive on its own, you're clearly sending stuff out regularly which is more than a lot of people do. I'd be worried about wearing out my mailbox but you must have a thick skin by now.

Free stuff hitting harder than paid tutors. That's always the way it goes sometimes. Those big companies overcharge for basic stuff you can find online. Khan Academy's math stuff is legit, straight up saved my nephew too. The problem is people think expensive means better, but it's usually just marketing fluff. Glad that kid stuck with it and proved them wrong.
