Read. The best way to become a literary critic is simply to read everything you can get your hands on, from the classics to pulp fiction. This will allow you to get a feel for different types of writing and writers and identify what you like and dislike.
Take a class. Taking a class in literary criticism, or even engaging in full-time study of the field, is a great way to learn how to appreciate works of fiction, and to identify themes and symbolism. Being surrounded by other literary critics is also a good way to hone your skills.
Join a book group. Book groups are a great place to share and express your opinions about popular novels as well as the classics with others reading the same book. Fellow book group members can challenge you to support your position and expose you to other viewpoints. Most book stores nowadays sponsor some type of book club.
Write and submit your critiques. To pursue a career in literary criticism, you'll need to make a name for yourself in the literary criticism field. Try writing a critique of a novel or book and submitting it to literary review magazines or websites for publication.
