Neil Killion is a psychologist and former management consultant, who for around twenty years founded and ran his own outplacement company in Sydney, Australia. In this time he interviewed thousands of redundant employees from a wide range of organisations and slowly made several key observations regarding major change in people's lives and just a few key years. He eventually turned this into a brand new theory of life. This represents a significant new addition to knowledge with its own terms, icons, research methods and form of prediction. The theory is known simply as "Life Cycles".
He has now written four books (Life Cycles, 2008; The Life Cycles Revolution, 2013; Life Cycles - Relationships, 2018; Life Cycles – Coincidences, 2020). All books are multi-award winners and he has won the Silver Medal, Philosophy and Religion at the Readers Favourite Awards. What makes this theory different to all others is that it is fact-based, using detailed biographical analysis and is thus scientifically-oriented and not a belief system. He has conducted numerous statistical validation studies in support his claims.
