In the summer of 2012, Robin Williams wrote a note in the inside cover of his Twelve Steps book, just a short sentence detailing what he hoped might be his legacy. "I want to help people be less afraid." Two years later, he died by suicide at the age of 63; a tragic, traumatic end to a brilliant life. Williams, known for his quick wit, his genius, his ability to always raise a smile, was no doubt incredibly afraid in his final days, unable to work out why his brilliant mind was, as he must have seen it, letting him down.
