Just look at JK Rowling.
In April, Rowling retweeted writer Melanie Dione's tweet, which urged people to finish their creative projects, regardless of whether or not they were sure anyone would watch, read, or listen to them. "There were so many times in the early 90s when I needed somebody to say this to me," Rowling wrote.
The author struggled financially before the "Harry Potter" series took off, Business Insider previously reported. She also received a ton of rejection letters before her fantasy series was picked up. However, she kept working and has since gone on to become one of the wealthiest people in the world, according to Forbes.
