It goes without saying that none of us will be blessed with MacKenzie Scott's astonishing wealth. But all of us have the chance to copy her astonishing generosity.

Why it matters: Scott — who walked away from her marriage with Jeff Bezos with Amazon shares worth tens of billions — has given away a staggering $12 billion in just three years, and plans to keep giving until it's mostly gone.

• She's quickly overtaking fellow billionaires.

Her actions offer 3 key lessons for us all:

1. Be astonishingly generous: After her 2019 divorce from Bezos left her with about 4% of Amazon, Scott publicly pledged to donate her most of her fortune. All of us have chances to give our time and money with similar abandon. 
2. Put your money — and time — where your heart is: Scott — who is in the minority as a woman billionaire — is directing her wealth toward specific causes she cares about, like providing health care and education for women and girls. Some 60% of the organizations she has given to most recently are women-led.
3. Do good without fanfare: Scott is giving away money with no pomp and no strings attached. There's nothing better than a great deed done quietly. This can be as small as a kind compliment or anonymous gift. 

• Consider this: The Chicago YWCA, which runs a rape crisis hotline and helps women find jobs, had been struggling when, one Monday night, someone from Scott's camp called and said she'd gift the organization $9 million. That was it, The New York Times' Nicholas Kulish writes.

Oh, and you don't need to be super-rich to be super generous.

• As we told you in Finish Line, America was the world's most generous country this past decade. That cuts across class, race, gender and age.
• And you didn't just give money. 72% of you helped strangers and 42% of you volunteered your time.

The bottom line, in Scott's words: "Helping any of us can help us all."

Here are four of the most generous people in America's history:

• Andrew Carnegie, who made his fortune through steel in the 19th century, gave away 85% of his money before he died. It was the equivalent of $77 billion today.
• Warren Buffett has a net worth of $115 billion, and has pledged to give 99% of it away before he dies. So far he has donated $46 billion, much of it to the Bill & Melinda Gates Foundation.
• Bill Gates and Melinda French Gates plan to give away most of the Microsoft fortune. Their lifetime giving has already topped $50 billion. Even more notably, they've gotten other billionaires to commit to donating their wealth with the Giving Pledge.
