Yahoo CEO, new mom prioritizes God, family, work

>>> yahoo!'s new ceo, 37-year-old marissa mayer , is one of the country's most high-profile working moms. so how is she adjusting to her pressure-packed job and being a new mother? we got exclusive access to mayer 's first interview about how she's juggling it all. nbc's diana alvear has more on that. diana , good morning.

>> reporter: good morning. two months after the birth of her son marissa mayer gave her first and last interview about life as ceo of yahoo ! and new mother. interviewed by "fortune" magazine in front of a crowd of invited guests, mostly women, marissa mayer focused on her two new roles

>> i knew that the job would be hard, and i knew that the baby would be fun, and i -- and i -- and the thing that surprised me, and really puzzled me so, is that the job is really fun. like yahoo ! is -- yahoo ! is a really fun place to work, and the baby's been easy. the baby's been way easier than everyone made it out to be.

>> reporter: mayer was just 37 years old in july when she was named ceo of yahoo ! becoming the youngest ceo of a fortune 500 company. she was also six months pregnant and announced that she only planned to take a week or two away from the office. in contrast, in a 2008 interview on "today," mayer , then a google executive, seemed to back longer maternity leave.

>> i mean, basically said, you know, a baby and a googler should have their parent at home for six weeks or three months, and it should be standard from that child's point of view, and i think that means that ultimately it's a really supportive environment for women, but it doesn't necessarily mean special treatment for women.

>> reporter: on september 30th came the birth announcement via twitter from mayer 's husband and true to her word, two weeks later, the new mom tweeted she was back at work.

>> what's the most important thing that you do to get it all done?

>> you have to prioritize, and i do -- that's one of the reasons i haven't been talking and i'm going to go back to not talking.

>> reporter: all mayer has only run yahoo ! since july, her management style is clearly clicking with investors. theistic's up 18%. as a wisconsin native, she cited legendary green bay packers coach vince lombardi for his drive for success and winning.

>> vince lombardi says, you know, in my life there are three things, god, family and the green bay packers , in that order, right? and, you know, i think for me it's god, family and yahoo ! in that order.

>> and in a few hours, mayer joins a group of ceos for a meeting with president obama about the ongoing negotiations over the so-called fiscal cliff, and then she eel have just enough time to get home for her son's two-month birthday on friday. matt?

>> diana , thank you very much.
