Please forgive my ignorance, I don't know what the determinants are in the book. So feel free to enlighten me.
@cashflow Agree about the nothing to do, thats why I now struggle with retirement being the time when passive income covers expenses. The idea of doing nothing is not what retirement is about for me.
To me early retirement is when you have complete freedom to live the life you want. Some people may want to work for the rest of their lives, if they work for this reason, no matter what their income, expenses, perhaps they could be considered early retirees.
Personally I hate the stock market etc. If I was involved in that I wouldn't consider that passive income because I would only be doing it to earn money, and I would be working playing with spreadsheets, because if I had the choice i wouldn't spend time on the markets.
I also have a degree of sceptism about the markets and banks, making myself as self sufficient as I can and being an asset to my family, community, these seem to be of much the same amount of importance to my retirement goals as the financials.
I like the thread here about Lulu and how life is temporary. Many people have put money into the markets and housing, only to have it taken away from them.
Every day around here I see another house bulldozed,a house that in may case people have saved for all their lives, and gardens to provide food etc all gone in one day. They get paid half the value of their properties, and have to start all over again on small properties.
I guess the answer is to be adaptable and have as many skills, different supports as you can gather.
These are just my thoughts and with Cashflow I again agree to each his or her own.
