As The Tubes sang - What do you want from life? Retirement is just a part of it.
I started planning for retirement back in my 20's, even though I never expected to live long enough to enjoy it. (Bad health problems in my youth and early 20's). Ignored all the "settled wisdom" of retirement planning, did my own thing. I was a mainframe computer programmer for my entire career, never a manager (by choice). By 2005, I became a contract programmer, just to avoid the corporate politics. From 2006 to 2020, I worked around 60% of the time, on average. Saved all I could, as you never knew when the next contract would be. Retired due to the COVID epidemic at 63 1/4. (I had planned to work until 64, but stuff happens . . .)
But lifestyle is key. An econobox car gets you to where you are going just as readily as a super luxury car, but saves you lots of money for other things. I'd rather look poor and be rich over looking rich and being poor - YMMV. Aftermarket timeshares instead of a second home. ect. (The Frugal Gourmet concept. I picked this up from a book published in 1976 - Andrew Tobias'
The Only Investment Guide You'll Ever Need.) I paid taxes in advance (when every investment planner in the world seemed to say that doing that was stupid) to convert all my IRAs (and rolled in 401Ks) to Roth IRAs. Bought a nice house in a nice neighborhood in 1992 with my brother (both of us are conformed bachelors), when houses in D/FW were going for a song. (Still living there!)
Why do I mention all of this? The result has been a champaign retirement on a beer budget. (Or maybe just a imported beer retirement on a domestic beer budget

) Car payment? Haven't made one since 2003. Mortgage? Small one kept deliberately to act as a block for housing identity theft protection (a quirk in Texas law, not applicable anywhere else). It was taken out against the paid for house, with the amount used to buy an investment, (which has over tripled since then). I have always been substituting capital for cash flow, so in retirement, I need little cash flow. Utilities, food, gasoline, annual house taxes (which are frozen), various insurances (house, car, and health) and a $260 mortgage. Everything else is luxuries, for which I can spend as much, or as little, as I please (other than the timeshare MFs) from my monthly budget. Any major purchase from from my capital investment. As for cashflow, I bought 3000 shares of Altria (the old Phillip Morris) for the dividend. It is now slightly over $1000 a month, tax free because it is inside the Roth IRA. (And I don't pay any income tax. My taxable income comes in at under the standard deduction, so no taxes owed. Bonus for playing the game and winning. . .

This may not be your lifestyle, which is fine. Re-read my first line above. . .
