Book Recommendation - Making a Literary Life: by Carolyn See

This book covers the gamut of writing from the decision to become a writer to the challenges of publishing your work. The author is a novelist, memoirist, creative writing teacher and critic. Included are much more than the building blocks of a novel; strategies to protect your emotional self so you can write effectively—such as pretending to be a writer, building a support network, dealing with “helpful” friends who aren’t helpful at all. and handling rejection slips, etc.

I recommend you give it a read.
