What's harder for you to come up with, book titles or character names?
For sure the book title is harder. It’s so immediate, so vital as a first impression, akin to the book cover. You can draw a reader in or shoo them away. The names of characters, while important are rarely deal-breakers as far as someone picking up the book or even continuing to read. Interesting and meaningful character names do not necessarily matter in many cases and analyzing why an author named a character yields few results except in obvious cases like Voldemort.
In fact, obscure or everyday names are chosen more often than not to no ill effect. I sometimes
choose names from the credits of a movie or by combining first and last names I’ve heard. Human names are easy to come by and many are unique and interesting or common and easy to remember. Titles that tell you something about the story are rare and give so much of a feel to the entire text, especially before you have a completed cover. It's hard to overstate the pressure I feel when choosing a book title.
