Be a good rolemodel and give her good (sometimes mean) advice. There is plenty of "just be yourself just do what you want" etc everywhere and if you don't point her in the right direction, nobody will. I mean it.
Dads are too afraid of alienating their daughters to give tough love, and they're right to-- as soon as they do, every single other person tells them to rebel and become a degenerate.
But she will listen to you because she respects and wants to impress you.
Just think, what would her dad (assuming he's a good person) want her to do, then guide her in that direction. Incidentally it will also make you his favorite person.
