July 21st.
This date is important to me for three reasons.
First, at 12:01am on July 21, 2007 I was a recent high school graduate, counting down the days until I started my first semester as a college freshman, standing in a Barnes & Noble with my little sister and and cheering with a crowd of hundreds as cardboard boxes were opened and copies of Harry Potter and the Deathly Hallows were lifted into the air. Years of reading and waiting were coming to an end as I entered adulthood, and the Boy Who Lived was facing off against He-Who-Must-Not-Be-Named for a final time.
Second, at 3:00pm on July 21, 2012 I ended my final shift as a Hogwarts student. I took off my robe, sweater vest, and Gryffindor tie and left the castle halls. I had graduated college a year previously, but now I was leaving school, leaving Florida, and achieving my childhood dream of moving to New York City and working in the film industry. Little did I know about what the future held for me. A literally rat infested apartment, Hurricane Sandy hitting the city (I thought I left Florida and the hurricanes behind?!), and the many, many, late nights and early mornings required when working on a film set.
Third, at 5:07pm on July 21, 2016 I walked to the mailbox, slid in the key, and opened the small metal door to discover a cardboard box wrapped in white tape covered in Inkshares logos. My heart skipped a beat, and I didn’t even wait until I was back in the house before ripping the package open. Nine years after I held the final Harry Potter book, a book I wrote was sliding out of it’s shipping box and into my hands for the very first time. 
Thank you, Inkshares. Thank you, Nerdist. Thank you, every single person who backed my dream, believed in my book, and brought me to this moment. If anyone told me a year ago that this would be happening today, I never would have believed them. I wrote a book, but you all made its publication possible. Thank you.
This is only the beginning.

(Rick, I see your photoshopped mustache from 400, your abundance of dinosaurs at 500, and raise you a writing space and an abundance of mustaches.)
(hope you've got a t-rex shirt ready, Rick, I'm sure you'll be crossing 500 right on my heals.)
