“A sort of highly-gifted one” is an autobiographical testimony that narrates all my life, my course of “highly-gifted” (diagnosed in early childhood). “A sort of highly-gifted one” because I am a kind of highly-gifted, representative and at the same time singular. Everything is told under the psychological aspect, without self-censorship, always with the subjective look of who I was at each moment. I have conceived this book as a long version of the lectures that I give regularly, like in the opening of the “Surdouessence” symposia that I organize. Surdouessence is also an association that I created for the accompaniment of the highly-gifted people.
