Is this quote authentic? "Surround yourself with people who make you happy. People who make you laugh, who help you when you're in need. People who genuinely care..." - Karl Marx

I've seen this all over the place, but no evidence that Marx actually said it. Also, as a bonus, this is one attributed to Sophocles: All a man's affairs become diseased when he wishes to cure evils by evils.

Any help would be greatly appreciated.
