Looking for books on market writing, or books that deal with writing anxiety. I have a problem with my writing sounding "too academic" and would like to learn how to make it more interesting.

Any recommendations would be greatly welcome. Thanks! 

It's not a book, but I wholeheartedly recommend Brandon Sanderson's podcast Writing Excuses. Brandon Sanderson is not only a brilliant writer, but he's also breaking down writing and examining it like no one else imo.
