Last year I participated in the 2016 Pop Sugar Reading Challenge. It was fun, but I definitely did not complete it. This year one of my goals for the new year is to actually complete the challenge. This challenge suggests 40 different "genres" of book to read, such as "a book with multiple authors" and "a book set in a hotel." Pop Sugar also added an advanced extra 12 books, for those who complete the list early, which would come out to one book per week.
I like that this challenge adds variety into your reading list. It really allows you to read whatever you want to read, as long as you are exploring new choices. For anyone who wants to join me in the challenge, you can find a printable of the full list HERE.
