What have I got to lose?

Yesterday I rewrote a two page Prologue for a manuscript that evolved from a short story I wrote 13 years ago. Today, not motivated to much - have a stomach something - after some online learning while straightening my in-basket I came across an invite to the April 14 Galaxy Press 29th Anniversary of the Writers of the Future Contest. I must have gotten invited because I submitted some work to Galaxy that was encouragingly rejected. Although unable to attend the invite motivated me to think about submitting the short story that birthed the manuscript but haven’t even started preparing my entry and my brain is already doing the “it's not good enough" ditty, so I replied, "what have I got to lose?"
