Leverage

 One of the recognized forms of leverage is the leverage of borrowing money.
Millions of people struggle financially because the power of debt leverage is used
against them.  Good debt makes you rich and bad debt makes you poor.  I retired
young and rich because we were deeply in debt, deeply in debt with good debt, debt
that made us rich and financially free.  We used the power of leverage, we did not
abuse the power, nor do we live in fear of its power.  Instead we respect the power of
leverage and use it wisely and cautiously.
