Write because you love to. Write because you got a message you wish to share & write because writing, though it may be draining at times, Its very much fulfilling. So write with a goal & don't give up - don't let anyone tell you "you can't write!"
It's refreshing & daunting. But having them find the books interesting & worth the read, that the books impacted them positively - then its a welcome delight.
Yes I do read the reviews. I am grateful for both good and bad review. The good I smile, the bad I tell myself "Not everyone will like the book" and look forward to bettering my other books.
