"Don't underestimate flattery," says Ivanka Trump, the Celebrity Apprentice star and executive vice president of The Trump Organization. Attend speeches or panel discussions featuring your more senior executive, then follow up with an e-mail, which may open up a dialogue, Trump advises. Also prove you're worth her time by cultivating an air of diligence—show up early, stay late, and volunteer for the scut work everybody passes off. "Stand out by taking ownership over things that aren't being done," says Trump. "It's less about showing people how smart you are and more about taking initiative and making the system work."
Rule #1: Dress like you belong there. For weeknight games, work attire is fine, though you can't go wrong with jeans and a blazer, suggests Petra Pope, senior vice president of event marketing for the NBA's Brooklyn Nets. Rule #2: Don't talk shop (or order a cocktail) unless the boss does first. Rule #3: Don't pretend to be a die-hard fan if you're not.
