I don't believe in the concept of coincidence or luck personally... some say that makes me a fatalist, but in my mind it's just all interwoven energy that ripples out and directly impacts all other energy. Spelling and language in general are a very interesting area to ponder. The fact they call it "spelling" makes me think language was inherently designed with the potential to weave illusions. Just look at legalese and how the same words can be used and interpreted in so many different ways that it becomes very clear it's intentional to allow arbiters of the law to, in most cases, come to their own conclusions. Just remember the famous Bill Clinton quote, "It depends on what the meaning of the word 'is' is."
