While I agree, this should be the plan earlier than 65, if possible.
Also believe that if you play your cards right, you should not be retired at 65. You should be hitting an intellectual stride and really contributing to your field.
My grandmother didn't retire until she was 80, had nothing to with finances.
Vint Cerf is 81 and still working at Google. Robert Caro is 89 and still writing about Johnson. Harold Bloom was 89 when he died.
Stop letting this hustle culture fool you, stop letting this "retire early" culture fool you.
Not interested in working to death, wanna enjoy my family
