Do…have confidence. “Guys find confidence very attractive and just remember if you're nervous, he probably is, too!”—Josie Lauren, Make It Or Break It 
Don’t…try too hard. “The quickest way to get a guy to head for the hills is desperation.”—Jennifer Stone, Mean Girls 2
Do…play a little hard to get in the beginning. “You want to come off strong and grounded. And never let anyone take advantage or walk all over you, no matter who they are.”—Cassie Scerbo, Make It Or Break It
Don’t…play dumb. “Guys may like feeling superior, but holding your own is far more attractive in the long run.”—Daniella Monet, Victorious
Do…balance compliments with playful insults. “You don't want to seem too eager but you also don't want him to think you're mean.”—Meaghan Martin, Mean Girls 2
Do…flash a big smile. “Works every time!”—Claire Holt, Mean Girls 2
