Title: Zen in the art of writing
Author: Ray Bradbury
Zen in the art of writing is a fantastic book by a fantastic author. In this book Mr. Bradbury describes a lot of his own journey into writing, and along the way he hands advice to (aspiring) writers on what to do and what to avoid (things he learnt during his prolific life).
For me this book was a delight to read and gave me the incentive to keep going no matter what.
