Title of a book is very important. While there may be people who will give your story a chance without judging it by the title and cover, there are plenty more people who won't. Sometimes, I am one of those people too. Especially if I don't know anything about the author and I am in a bookshop, then if the title is unappealing then I won't risk wasting my money, but move on to something that seems more promising. Not fair, but that's the way it works. So the title is important. Some people start with a title, others decide it fairly early on in the book, but in my writing history, titles rarely come at the beginning. In couple of books, I've had titles decided fairly early, but usually all WIPs are known either by the main character's name, or by the place where take place. I do try to think about what the title should be, but not really agonize over them because I feel that until the book is good enough to be ready for submission, it's not really worth worrying about. Worrying about the story will probably pay off better in the long run. When do you come up with your titles? How do you find them? Do they come easily to you, or do you have to spend a lot of time finding the right title?
