To me, the term "early retirement" is an overrated thing.
I feel the same too. It seems too good to be actually true. Or it is a dream of escape from a job that the person never wanted to do. So they think of retiring early and escape the pain in a dream.
For those who are passionate about what they are doing, they would continue to work on their fields even after they retire.
If they are actually contributing to their field of work, they will be paid well, they will have the enthusiasm to continue their work and their mental health would not worsen.
Still investing should be done along with work side by side but it does not necessarily mean that everyone can retire early, most of them can never do this.
These are really solid and important points because if you are having good reputation into your work, and you are feeling comfortable then surely you need to enjoy this for as long as you can a which will give you extra money more experience and many other positive things which are not possible through you are going for the early retirement even many will be not agreed with this but still this is important and good way of keeping yourself busy.
We have too many examples as peoples are taking not retirement even they are facing problems, but they love to keep themselves in challenges and this is also way of their survive for long time having early retirement and going through for easy life usually have other consequences as well.
