Would anyone of sound mind refer to themselves as "a genius"

Almost geniuses themselves!

Well, he's looking very like a genius - he plays golf all day and tweets all night and the USA is still functioning

They say there can be a very fine line between genius and insanity though, don’t they? (Not saying which side of the line,,,,,,]

From today’s DT Lettersv column:

– Perhaps, by Schopenhauer’s definition, Mr Trump’s self-declaration is correct: “Talent hits a target no one else can hit. Genius hits a target no one else can see “

That's brilliant.
