If it meant you could retire in your 50s....

Would you (could you) drastically change your lifestyle? Spend a lot less? Travel less? Cook more and go out less? How much of a change would you be willing to make to make early retirement happen? Or would it not be worth it to you to give up so much?

I recognize this isn't a question that's even an option for many of us. But for those who do have the choice, is this something you've considered?
