Everyone must start somewhere. That somewhere usually include the number 1. Be it in the form of the First step, First Moment, First Thought, First Ideas... This is the culmination of First's for me. First book, First time publishing (self-publishing), First time giving away a book for strangers to read (gasp!) and now, my First Sale. From here on out, everything I do as a writer (should I continue to write) will be the First for THAT particular book, not for my life as a writer.
Correction. This is the culmination of good Firsts for me. I still have to get that First bad review, that First one star, that First moment when someone tells me they hated everything about what I wrote. Waiting for that is worse than waiting for all of the good Firsts.
Le sigh, but it is a must. Although I don't hope for it in general, I know it is to be.
