The tale of Arthur and wishful thinking

I got stuck in a rabbithole.... again... I found the tale of Arthurian, well i broke it down and found the true tale.. I know the majority will never find the pieces,but those who do.. Its lovely to look at..

Can we change who we are? Its a simple question. Remove the ideals of wishful thinking and ask yourself, do you truly think you can change?
The tale of Arthur, was made on ideals.. Yet in the end he fell, do you think we can change?
