JoshuaSpodek, you should absolutely feel safe here sharing your success, yes! I can hear the celebration and sharing (versus showing off) in your voice :)
Congrats, again, on succeeding in completing your writing, putting your work out there, staying committed through the marketing piece, and on the commercial success! It must feel truly amazing to have your book displayed in amongst other well-known ones, and in such a major shop to boot.
I've had wonderful success too, but will provide the caveat that this has been with some projects and not others. Thus, I'm not entirely comfortable perpetuating an idea of "formula applied = commercial recognition." Some amazing books see this; some amazing books well marketed do not.
I encourage all of us to go ahead and feel all the feels in relation to our work—whether that be success in terms of income, success in terms of recognition, success in terms of achieving one's goal of so many words, success in terms of a sense of satisfying completion, success in terms of helping one person experience joy, connection, healing, thrill, or life change...as well as discouragement, frustration, humiliation, shame, embarrassment, disappointment, etc. It's all fair, all valid, all normal, all healthy. Good stuff.
Writing and putting our truest stuff out there is big soul work, it changes us. Even without the shiny stats for any one given project, there is so much goodness in completing our work (for our own souls) and offering it out (in case it gifts additional souls).
Every day I am so grateful for countless people who write—commercial accolades or no commercial accolades—because so much has helped me in profound ways.
