Definition of wealth

You say you are rich. You are wealthy.
You may be well off, but are you really wealthy?
There is a distinction, you know?

Wealth is a person's ability to survive so many number of days forward ... or if I stopped working today, how long could I survive?

The above extract is from Rich Dad, Poor Dad and attributed to Buckminster Fuller.

When I read this line for the first time, it scared me. I can just imagine how long I will be able to survive without a job. And more importantly, how well will I be able to survive? So today I may be better off that I was 10 years ago. But I am definitely not wealthy.

Are you?
