H0w much $$ is enough.

I don't think there is a one size fits all answer. Too many variables. Lifestyle, health, mortgage and other debts, and so on.

You get use to the taste of cat food after a while. 😜

As much as you acquire. Retiring means living within your means.

I'm trying a real life experiment on that now. I'll let you know in 10 years if I have enough now.

2 dollars if that wins the lottery. Otherwise it is based on your spending etc.

If you invest, save and plan for retirement, you'll do just fine.

Depends on a lot of things different for different people

Just really depends where u live. Just add up what u spend a month. Food and car. Electricity and water and gas. If your still paying anything off. My grandfather he lived off of a couple thousand a month. Now he had everything paid off that I know of. Didn't really buy stuff he didn't need. He didn't really travel at all.

A million if you budget well.

700 000 euros.

$3
Edit: I have no idea.
