The 7th year itch

​The 7th year itch is all about the phycological perception that people want change every 7th year.
​In 1984 I bought my very first house. Soon after my purchase the house market collapsed not to recover until the early 1990's. I was able to sell my house end of 1991 roughly for the same price as where I bought it for.
When in 2008 economic disaster struck, the house prices in the US and Europe collapsed. They recovered beginning last year with an acceleration of the prices this year. A nice 7 years after Lehman Brothers bankruptcy. 

​Austrian philosopher and teacher Rudolf Steiner created a theory of human development based on seven-year cycles that were associated with astrology.
My experience tells me that it looks like there is some truth in the "7th year itch" saying. It looks like people indeed get bored after 7 years and want to change (their lives, their environment, their relationships).  
Maybe we need to develop a new business model based on these cycles ;-) Why not? The world's gone crazy anyway.
