This is the second time I’ve seen this title (*On* Becoming a writer) on a blog, and both times I thought (admit I hoped) it was Becoming a Writer, by Dorthea Brand. That book is over 30 years old now (aka, there are really cheap used copies on Amazon), but as it was first published in 1934, I was astonished that it was the first book I remember reading (in my early days of imbibing writing books) that said things I didn’t remember getting from school.
Dorthea’s was the first place I read about morning pages, and the only place where a confident, experienced writer suggested, ‘Now, look back at what you’ve written in those pages. This is a clue to the type of writer you naturally are.’
It was my first touch of self-knowing, not as indulgence, but as a path to greater joy and effectiveness in your work.
