Self-improvement books are often wonderful. I have started reading them too, both to grow professionally and mentally. I'm so glad your selection is now more varied; I also write novels and often look for references. I think this book you've chosen will help you tremendously in understanding mental issues and outlining the book you're writing.
I wish you much success!
Hi @soldierofdreams great to know thay you are a writer and look for some references. I hope your book will make you don't caught by writer's block. I knew that finishing the draft is the difficult think when you have so much books as references. Fighting!
