I am about to start my very first book I am starting with a guided journal - My question is as it is my first book and I have no reviews is it best to niche down I was thinking of doing a self-help guided journal for ladies over 50 who have reached this stage of life and have lost their confidence and purpose slightly (empty nesters). Do you think this is a good idea or too niche? Thank you for any advice I am excited to start this new journey.
