re: Another “can I retire comfortably” question

Of course you can. You need to manage the difference between ongoing earnings and expenditures in retirement to ensure your money lasts.

You need to focus more on building nonretirement funds. If you are serious about retiring that young, then that money should get more priority than typical retirement type money going forward.

I "retired" at 55 by building up real estate funds that are not part of my retirement funds. I use those funds to generate income to cover the majority of my expenses and am delaying using retirement funds until I reach a more typical retirement age.
