"  We already love billionaire Warren Buffett for his championing of equality in the workplace and his ridiculously generous donations to charity. Now we might have one more reason to look up to him: He&amp;#039;s apparently grooming a 28-year-old woman to be his successor. Take that, sexists and ageists! Tracy Britt started out working as a financial assistant for Buffett just four years ago. Now? She has the office next door to his and chairs four of his companies, which collectively rake in $4 billion dollars a year. (Can we say, baller?!)  While attending Harvard for undergrad and business school, Britt honed her dream to work with a great investor who would also be a teacher and mentor to her. (Hmm, sounds an awful lot like her current boss.) But, when she shared this dream with her classmates, Britt wrote in an essay on LeanIn.org, one of the guys scoffed at her for being naive\u2014and we hope that dude feels like even more of a jackass now for trying to shut her down.  Britt&amp;#039;s journey proves that hard work and following your heart\u2014no matter what the haters say\u2014really does pay off. Tracy, we&amp;#039;re in awe.  Want more from Natasha? Follow her on Twitter or find her on Facebook. Photo: LeanIn.org "^^<http://www.w3.org/2001/XMLSchema#string>
