I read two books that each included stories of other twice-exceptional individuals. Reading them really helped me recall and relate aspects of my life to their stories, forming more of an understanding of HOW I am twice-exceptional. The two books are very approachable, but I suggest the reader takes time to reflect and add personal notes while reading them.

• Your Rainforest Mind by Paula Prober

• Being Twice Exceptional by Melanie Hayes

Also, check out Dabrowski's Theory of Positive Disintegration. I very much relate to that as a 2E.

I’d also tell your friend to keep exploring! Doing the work to better understand is what counts, instead of accepting things as they are. Twice/multi-exceptional people have more complex layers than most that will unravel as they reflect and accept who they innately are. And we should give ourselves the time and space for that to happen.
