Diary of a Madman

So, where it all began... I was once on a copper trip with my grandfather in the Upper Peninsula in Michigan, when I found gold! Yes, a small amount of Gold! But what the gold was supprised me, it was a lock and key for a book, not just any book though, but a diary! The diary was bound in a redish purple leather that reminded me of a limousine's chairs. I oppened it on the way back to my Aunt's house, when I saw what the writing looked like, it was in scribbles, so this is all I could make out:
