I did feel something coming, but was it luck?

Several days ago I wrote that I felt like I was going to have some luck this week in terms of a response to my writing. Well, I did get a reply from an agent. So in that sense I was right. However, it was a standard 'thanks, but no thanks' rejection letter. Now, because I'm incessantly optimistic (or I don't like to be wrong), I'm thinking about how that rejection could in fact be lucky. Maybe it's paved the way for the next one to be an acceptance; maybe I should take the stock advice offered in it about getting (another) manuscript assessment; maybe I need to hit some lucky number of rejections before fate/destiny/the universe/God/whoever sees fit to publish my book. So many possibilities and soon my fingers will start to hurt from being crossed all the time.
