Really! Read everything and anything. Read for pleasure. Read to learn.
I’m not saying finish the book if you just can’t after chapter 2. But if you can’t get past chapter 2, read the last two chapters to see how it ends.
Then, put the book in one of three piles:
Keep- never touching again. I have it just for a conversation piece.
To be read- the ending makes me want to read it. I’ll wait until I can wrap my brain around it.
Toss- I don’t mean throw it out. But instead donate it to someone somewhere.
Just enjoy. And if you read more of one genre than another? Who cares. As long as you are enjoying what you read.
