The difference is within the realm of chance?
What does realm mean here?
While the dictionary's open, note the pronunciation. The word shares its derivation, but not its vowel sound, with 'real'.
Try this definition:
"the region, sphere, or domain within which anything occurs, prevails, or dominates:"
Do you think "chance" might have this type of "realm"?
I don't understand what you are trying to rewrite, or why "business success" is supposed to equal "difference is."
This is the first time you have mentioned business in this thread. It doesn't appear to have any relevance at all to your original question.
