I think it's made reading much more accessible to everyone. Not everyone has the funds or ability to pick up a physical book from a library. Also, e-readers often have features that help people with visual impairments.
I do read my reviews. I come from a background full of facing criticism (the good, the bad, and the constructive). Though bad reviews may hurt my feelings, if there's a valid reason why someone didn't like my writing, I can take their words and improve. I also try to remember that as a human being, I am a work in progress and I'm not going to please everyone.
Don't give up. Don't worry about perfection. Just keep writing.
I took a long break from writing fiction. I opted to be a content writer for a long time. I still enjoy content writing, but it didn't nurture my soul the way fiction writing does. The only reason why I stopped spinning out fantasy and sci-fi was that I stopped believing my dreams could come true. Don't give up on your dreams. Shoot for the moon.
