I'm Nicole Lapin, the only financial expert you don't need a dictionary to understand.

It's time for some money rehab. Here's our weekly roundup of the biggest headlines on Wall Street and how they affect you and your wallet.

Last week one of the greatest minds in investing, Charlie Munger passed away at 99 years old.

Munger was Warren Buffett's business partner in their very successful company, Berkshire Hathaway.

Side note, Berkshire Hathaway is a company very much defined by its structure.

The company owns stock and equity in a variety of public and private companies.

The whole company is also a publicly traded company with two classes of stock offerings,

Class A stock and class B stock.

Now one share of class A stock is worth a cool half a million dollars.

Seriously, class B stock is worth a more modest $300-ish share.

Because of the structure, Berkshire Hathaway functions almost like an exchange-traded fund

or E.T.

It gives investors exposure to a diverse set of companies without dealing with the sorts of fees that mutual funds have.

But the biggest draw of buying Berkshire Hathaway is the access that investors got to investments guided by Warren Buffett and Charlie Munger.

Together they hone their investment strategy and have one of the most successful track records of all time.

And their friendship is goals.

Buffett described Munger as the architect of their success and himself as the general contractor.

They've known each other for over 50 years and beyond creating billions of dollars in wealth for both men, it also seemed to bring them a great deal of joy.

When Buffett and Munger weren't in the same place, they spoke on the phone for several hours every single day.

During the last few months of his life, Munger wrote a piece for

C. NBC with his three rules for work satisfaction.

And I want to read them to you.
