By age 25, Isaac Lidsky had lost his sight to a rare genetic disease. Despite years of degenerating eyesight, he graduated from Harvard at age 19, clerked for Supreme Court justices, and started a company. During this poignant TED Talk, he talks about how his blindness actually helped him. Even if people can see, they distort reality in their own mind. They make assumptions; fall for leaps of logic; imagine the worst; and harbor bias. Isaac challenges us to let go of these notions and become active creators of our own reality. As Helen Keller said: The only thing worse than being blind is having sight but no vision.
