Thanks a lot for the feedback :) I was going to say no, but you know what, I'll give it a honest try for the 9th book. I can probably afford it now. I've gotten plenty of similar feedback before too. Grammar issues (English isn't my native and I'm not good at natural languages in general). Bland covers, like you mentioned. Marketing strategies, many which I do not wish to try (for ex: buy a domain for my blog and ebooks). There's just too many things to follow/maintain. Researching, writing the book, reviewing and editing it, revising for later editions, etc are painful enough. I love the feeling of completing a book and seeing sales coming in, which so far has kept me going. All I wanted since leaving my job was sustainable income and if I can maintain current sales, I'm more than satisfied. All my ebooks can be read for free online. I get most of my sales when I post about a new book on social media for free download. Both leanpub and gumroad allow paying more than the specified price and readers are willing to do so.
