In a creative writing class I took last semester, the author originally gave up writing and his hope of being an author. He began to write a story for his own pleasure and posted each chapter on his own blog as he wrote them. People found it, grew to like it. They would point out mistakes and such and he’d go back and fix them. He finished it on the blog. One person couldn’t access it on his blog at one point, so he made a downloadable pdf version for free. Someone couldn’t download taht, so he made an ebook version of it, but had to put it on amazon so they could get it, but you can’t sell anything on amazon that’s less than $0.99. People started buying it via amazon and it got so popular that he took it to a publishing company.
tl;dr Never give up writing, even if it means it’s just a side-hobby for your own pleasure
the author actually worked at the same company as my dad for tech writing stuff. he said that once he made more off the book than he did at work he would leave his job. and he did eventually haha. the company went to see the movie together when it came out. don’t give up on the things you love doing! c:
