My parents provided me with all necessities but could not give me what some of my childhood friends had (fish tank, camera, watch etc) so I started to save on my lunch money. By the time I was close to finish a HS, it was very clear to me that if I want something I need to work hard and save in order to get it. My frugal ways of life style had developed. My wife had similar conditions at her childhood as well. I think that it was because of this part of my character what allowed me to retire early when I could not continue with highly physically demanding, well compensated job.
