Self-help extraordinaire Wayne Dyer has died. He was 75.

His family shared his passing on social media sites Twitter and Facebook Sunday.

"Wayne has left his body, passing away through the night. He always said he couldn't wait for this next adventure to begin and had no fear of dying. Our hearts are broken, but we smile to think of how much our scurvy elephant will enjoy the other side," the Dyer family wrote on Facebook.

Dyer, who was a psychotherapist and professor before launching his inspirational business, said he was diagnosed with lymphatic leukemia in 2009, according to CNN.

His first self-help book "Your Erroneous Zones: Step-by-Step Advice for Escaping the Trap of Negative Thinking and Taking Control of Your Life" was published in 1976, forever changing his life. The book sold millions of copies and led Dyer to pen another 30 books which offered positive and inspirational advice to lead an enjoyable life.
