Famous and Inspiring Quotations

I have decided to add quotations to my Blog. I'm not sure how often I'll change them on the blog itself but I intend to keep the past, present, and some future quotations here. I have catagorized them alphabetically by the person who normally given credit for the quotation. Send any corrections to me. I've obtained them from a number of different sources and unless I find out differently I'm assuming they are not under copyright.
