In a speed-round conversation with Fortune’s Leigh Gallagher, Ariel Investments president Mellody Hobson details some of the best advice she’s received.

  • Speak up (don’t let job seniority, company title or salary dissuade you)
  • Ask a lot of questions (can be a more effective way to influence another’s opinion)
  • Crouch to Conquer (sometimes it’s important to reign in your own personality)
  • Smile a lot (people want to work with people they really like…they want to work with people who are happy)
