this story is the same as what my cousin experienced, he retired early (at the age of around 35 years) now he is around 45 years old but there is an illness he is suffering from and he has to get proper treatment which quite expensive, so he sold some of his valuables and also withdrew his investment in shares.
as long as you can still make money, don't even think about retiring early, I know early retirement is everyone's dream but who knows what will happen next, you have to maintain your grades and productivity so that you stay healthy and respected by people.
Retiring at 35 years seems crazy, at least for me there is no chance to retire at such a young age. When reading the title, I thought at first the early retirement age would be around 55 years, which already 12 years below the official retirement age in my country. Which also would be my goal to retire before I become 60. I find it surprising that someone as young as 35 can already earn enough money that is going to cover for the rest of his life. Becoming ill and requiring expensive treatment is pretty common these days with people becoming much older. It doesn't really matter at what age we become sick, if we don't have enough saving in our retirement plan for it than we are doomed. That is probably why I would never consider retiring before the age of 50. There are still so many unexpected things that could happen in our life, that we would need a lot of money to account for it. Also, in retirement I would like to live of the returns and dividends of my investments and not touch the actual savings money.
