If one day you come into wealth, memorize these ten things by heart:

Don't tell anyone, not even your parents.
Pay off all your debts first, whether they are with friends, banks, or lenders.
As soon as the money lands in your account, don't rush to move it. Let it sit and think with a clear head.
Don't rush to buy a house or move to a more exclusive neighborhood right away.
Don't quit your job overnight.
No luxury cars or expensive whims for now.
Never get involved in business with friends, family, or acquaintances.
If you have children, do everything possible to keep them unaware of your new financial situation.
Maintain appearances. Let nothing in your behavior reveal that something has changed.
Be discreet with your information and avoid sharing your situation with anyone.
Most people who receive money end up losing it all precisely because they break each of these rules.
