Step 1: Walk to your nearest bookshelf, bookstore, friends house.
Step 2: Pick up a book.
Step 3: Get comfy and read.
Read until you forget where you are and are enveloped into the trance of a new world. One that is entirely not your own. Where you're not yourself.
Read until you cry, tears rolling down your face because you can't tell the difference between fiction and reality anymore.
Read until you can hear the character's voices and their quirks make you laugh like you're old friends.
