I also did FIRE - though didn't realise I was doing it until I stumbled across it online. I was able to retire at 52 and will live off my savings and my OH's salary until I can access my pension. I have not inherited a penny. How can I afford it?
I did a very, very stressful FT job for 30 years. I have two children but took only the minimum maternity leave (basically until the pay ran out, which was just 4 months back then ). My job paid pretty well for the area I live in.
We have lived in the same house for the last 25 years. We have had the kitchen and bathroom done once in that time. Do all the DIY myself. We are happy with the decor and furniture we have. Not interested in spending lots on carpets etc.
Mortgage was paid off five years early so we have been mortgage free since I was 42. This meant that the money could be put into savings every month.
No 'luxury' holidays . We went away every year but always SC, booked myself and using low cost flights. When the kids were small we always had two weeks always in SC with a pool, so we didn't scrimp, but I always shopped around rather than going on package holidays.
Never took out loans or built up credit card debts. Paid them off in full every month so no interest rate costs.
Switching insurances, broadband, energy providers etc regularly. No expensive Sky packages for stuff we didn't watch. No mobile phones on contract - I always buy a cheapish phone and use giff gaff bundles. I pay £8 a month for my phone bundle and it cost me £100 to buy.
We have two cars. Both very boring and low spec but they get me from a to b. Never used finance to buy them.
I food shop mainly in Aldi. I plan meals for the week. We throw very little food away.
Most importantly I have a husband who supported my decision to leave work. He could see how it was driving me into the brink of a breakdown. He works in a job he loves, though his wage is half what mine was. It would have been impossible to go down from two full time wages to one without the savings we have.
I know I am very, very lucky. I did have a well paid job. I have a supportive OH. I loved my job (until the final couple of years), though it was incredibly stressful and I worked crazy long hours and brought work home all weekends.
I made the right decision. had I stayed in the job my health would have suffered even more. I could have ended up with a lot more money in the bank but what I have gained instead is far more precious to me. The money may run out, the time certainly will. I chose time over money.
