Save Money to Retire Early

A few years back, a manager of mine, who had saved millions up to that point, said to me that I should enjoy myself with the money that I have rather than save it all like he had done. 

Recently, an older woman admitted to me that she had no savings for retirement as her philosophy was to, in-fact, enjoy her money in her youth while she still could and not wait until retirement to do so.

My questions to these people are the following:

• To the manager - Why were you still working at the time you told me this? If you have millions saved, and you're sharing with me that you're regretting not having enjoyed yourself more in your youth, why didn't you just quit your job and enjoy the money you had acquired up to that point while you still could?
• To the older woman - Why aren't you saving money in order to retire earlier to enjoy yourself without the constraints of work?

I save money not because I plan on spending it when I'm retired but because I want to retire earlier. While I love what I do, I increasingly want it to become a choice the older that I get. I would find it stressful to not have anything saved up for my future.

We live in a society that's all about "buying now and pay later" but that's such a bad way to live. Why would you sacrifice future time for something now? Isn't that how people get stressed out? 

No.

Don't sell your future. Save money now in order to buy future time.
