Really, all you need are two things:
First, this site – the homepage of Supporting the Emotional Needs of the Gifted.
Secondly, Daniel Goleman’s Emotional Intelligence book.
Well, you need my class, too, but I can’t print that here. One thing I sincerely recommend are film- and bibliotherapy to help gifted kids understand themselves.
The Feelings posters at KindleMental are fabulous and inexpensive. Love this company; love their product.
