Barbara Corcoran, real-estate mogul
Barbara Corcoran has built a $5 billion empire in real estate. She’s also an investor in (and star of) Shark Tank. So where did all that ambition come from? Dyslexia was a driving force, according to Corcoran. “It made me more creative, more social and more competitive. There’s a great freedom to being dyslexic.” The key, she says, is to not let school struggles or grades define you.
