How did we get to the <21 Bitcoins = rich> number? I see that number coming up all over the forum. In my opinion 21 Bitcoins cannot even buy you a small car in my country. 
From all the comments sofar, I like this the most :
If the amount of Bitcoins you have, can pay for every expense you have, without you having to work.
You have to be debt free, and be able to live comfortably on the Bitcoins you have for the rest of your life.
Depending on the lifestyle you are used to, this would be different for all people. Inflation is a @$%$... and living on any income, without a option to beat inflation, kills that idea for most of us.

For me being rich is having enough money to last the rest of my life without working plus having no debt with my home paid off and self sustaining utilities. Then having enough money in an investment that gives me an income of a few thousand dollars a month to live on.
Once I hit that point I will retire.
