Encourage her to build and create things. If she chooses the computer as her tool, all the better, but provide her with as many avenues of creation as possible (paper, sound, words, images, code, wood, ideas, etc) and she will find the one that's right for her. She is a teenager, I believe you are not her guide anymore, but you can (and should) be an amazing facilitator and her #1 fan.
