1) Estimate your monthly expense in "normal" scenario; such as $10k in today's money
2) Find a "hen" (pension, annuity, rental, .....) can make the egg every month at the number desired as long as you are alive
3) Buy insurance to pay for unexpected (LTC, Life, .......); if you need to claim it for yourself or your family, great; if you don't need it, think it as a "donation" to those less lucky who needs it.
4) Continue working (if you are doing something you like) or doing something fun till the last day of life if possible. You may make much more $$$ without pressure and with passion. If you make little $$ from "work", you have fun.
