this is a whole different subject, and one we've discussed elsewhere.
But I still don't get how / why you'd deprive yourself of everything just so you can retire earlier. Then what? Will you stop depriving yourself or sit around and get bored?
I save plenty but don't plan on not working for a long time. So we can do things we enjoy now while being comfortable in the future.
Every day I'm at work I feel like I'm dying a little more inside (4 days a week)
Every day I'm at home I feel alive and vibrant even if I don't actually spend any money.
I don't need stuff.. I need financial independence... and time.. those are far more valuable commodities than stuff or even experiences (which in general when I do spend it's on those)
