Ron Davis grew up labelled a dummy, yet despite what looked like severe learning disabilities he became a successful engineer, businessman and sculptor.
He was 38 years old before he could read a book cover to cover - once he discovered the key to his dyslexic mind.
He went on to use that information to help teach dyslexics to read.
His final 3 lectures are:
Dunedin - March 11
Queenstown - March 12
Nelson - March 14
