The wonderful and profound meaning of money:

No matter how much money you (think you) have or (think you) don't have,
there are limits on what you can buy.

All self-justifying and self-congratulating rhetoric aside, what you end up buying proves and demonstrates your
-priorities
-values
-identity
-religion and ethics

Cigarettes? Charities? Booze? Causes? Investments? Entertainment? Rent/Mortgage? Support of others? Purchases? Necessities? Luxuries?

When the time comes to prove who you you REALLY are,
how you spent the money you have will remove all doubt
to all observers.
