I retired at 47. I started planning for retirement the day I started working. I enjoyed summer vacation so much when I was a kid that I decided a life of leisure was the life for me! I'm not married. I don't have and never planned on having children. I live in a very nice but modest home that was bought and paid for long before I retired. I'm really not all that excited about travel. It's really all about saving and living within your means.
As for the cars, I currently have four and two motorcycles. I have retirement accounts, both traditional and Roth IRA's. I'm 61 now. I hear you guys discussing cars alot and it's always modern cars. For me vintage cars are where it's at! Most of my vehicles are still gaining value. In a few years I may decide to sell a couple of vehicles to finance a vacation home but we'll see.
Btw if you're wondering what I did to achieve all of this, I was a Police Officer. It's a job I wouldn't even consider if I were just starting out today. I understand that the cost of health care is a major concern for most early retirees but thankfully my health care was paid for which made retirement possible for me.
Again it's all about planning, saving and living within your means. Choosing not to have kids didn't hurt either.
