Question

So heres a question. I joined 2 reading challenges that need you to challenge yourself to read a certain amount of books in the year. I picked 100 for one of them and was told by a friend that wasnt very much. I picked randomly cause I have no idea either! I have never counted how many books I read in a year. I know I have roughly 1000 in my good reads but that is just some. So what do you think is a good number to challenge yourself to read in a year?
