suzyboo: i wasn't actually presenting Ron and Harry as factual characters, I'm not even a Potter fan.
However, I am a literary genius, obviously, and was presenting these characters as a commentary on the human perceptions of 'luck'. Characters in fictitious books are often based upon real life qualities exhibited in the human race and are anthropological to whatever extent, EVEN if those characters are created by a mediocre, unimaginative writer such as the lesser spotted JKR, they can be endorsed as commentators none-the-less.
Also, to keep in essence with the question, when discussing a fictitious theme, such as luck (which is no more real than the great dumbledore himself), I chose to use a fictitious situation, a kind of extending analogy if you like. Almost a hypothesis; tag "Imagine someone made you believe you had drank a luck charm potion...how would that change you perception of your day?" onto the original answer.
with love,
