Seriously. Don’t do it. Even if you have to write your book a thousand times, or get it back and every page is covered in ink, or you run out of ideas and your paper is literally filled with “potatoes” a thousand times.
Don’t close the document and never write again. Don’t put away your notes and fill your days with a meaningless day job and bad soap operas (granted, please get a job and a hobby aside from writing to keep from going insane). Keep pushing. It’s worth it.
JK Rowling was rejected by something like twelve people before she finally struck gold. She was consistently rejected and pushed away, before she finally hit it hard. Millions of kids now read her book, not to mention their parents. Don’t. Give. Up.
You could be the next JK Rowling or Steven King. Don’t expect to get that level of fame overnight, or even over the course of two years. Not everyone gets so lucky. But make sure you work hard, and aim for all the right goals.
Good luck, and get off my blog. Don’t you have a book to write?
