The world's top 20 billionaires under 35

In case you weren't already feeling sad about last Friday's paycheck, a top 20 list of the richest people under the age of 35 came out this week.

Topping the list is Facebook founder Mark Zuckerberg. The 31-year-old is worth a staggering $41 billion.

Zuckerberg is one of 3 Facebook-made billionaires on the list. The other two are also in the top five; Dustin Moskovitz trails Zuckerberg for the number two spot, and Eduardo Saverin ranks fourth with an estimated net worth of $5.3 billion.

This year, six of the 20 are women.

Huiyan Yang takes the third spot, making her the richest woman on the list. The 34-year-old vice chairman of Chinese real estate developer Country Garden Holdings is worth an estimated $5.9 billion.

The richest self-made woman in America on the list is Elizabeth Holmes, who founded blood-test company Theranos at just 19-years-old.

The youngest person on the list is Snapchat chief executive Evan Spiegel. At the ripe age of 25, Spiegel has already earned $1.9 billion earning the 15th spot on the list.

Airbnb has three billionaires who made the list -- who each boast a net worth of $3 billion.

While 9 people on the list can thank the tech-industry for their wealth -- 11 of them can thank their wealthy parents.
