Yes, most books have been written by men. Still, I wouldn't use that overarching sweeping statement that could be considered racist/race-baiting and misandrist that detracts from what starts off as a very interesting article.

Unfortunately, you have leaned into the sympathy Olympics. I don't think any successful woman ever said I can't achieve success because I am not a man or I am not white.

It requires a positive mindset that you can and will be a successful writer. Dedicate yourself to writing every day and honing your craft. Treat the word impossible as nothing more than motivation, to be the best version of yourself.
