People who are conservative like you probably overestimate how much money they need to have saved. Plus how much less life can cost if you're single without a family to provide for.
During the pandemic, I took almost a year off from work of any sort. I had eliminated all of the expenses I had that I wasn't deriving real value from, and estimated how much I'd need to have in the bank to afford the time of no income. Then I saved up that amount.
At the end, I'd overestimated by about 4x and learned a great lesson about how much money I actually need to live in the manner that I prefer.
If I had spent a few months really tracking my spending at a granular level, I think my estimate would have been much closer to correct.
