Sometimes you want your Kindle book to appear in specific categories that don’t appear in your own pick method. If this is the case, just send an email to KDP support (at email@example.com) specifically telling them where to put your book. For example:
Hello awesome Kindle person!
Could you please add my book “15 secrets successful people know about time management” (ASIN: B016FPTIZ6) into the following 2 categories? Thank you in advance.
