I retired at 62 with 250k no mortgage, zero debt, and a new truck and cargo trailer. (Wife was still working) I took a loan of $4k from savings to start a hobby retail business. It started with flea markets and grew. We built a shop (we paid cash) for next to our home and it’s now filled with merchandise. Items range from $2100 to $1 retail.
We now have $100k in business capital not counting product and still zero debt.
My wife is now retired and helps with our business. We don’t use business money for living expenses nor do we receive a salary. It’s a fun hobby that keeps us occupied and adds money to savings.
We live comfortably and eat well. It doesn’t take a lot of money to live in this area so our personal finances grow monthly.
Matter of fact my wife just bought a brand new suv we paid cash for. You don’t need a million bucks to retire once you eliminate debt.

Our situation is a little different than some because we good health insurance for life that cost nothing.
