I only say training in place of practice because that seems to be the more accepted term in soccer. Her coaches and academy refer to it that way instead of as practice and so do I.
As for her "dream" to play college soccer, that started with her when she was 8 years old and went to my wife's alma mater to watch a game. She knew her mom played there and that's what she wants to do to. It may pass or it may not but 3 years later it is still her "dream." I wonder if you have kids to make that comment since all three of my girls have dreams. They change constantly but whatever they want we support and provide them with opportunities to explore them. My oldest wants to be on broadway and started trying out for school plays when she was 10. Three years later, she's still pursuing it. Again, it may pass, but it doesn't mean we shouldn't give her the opportunity to try it out with voice lessons, dance lessons or auditions for plays. Same with my girls that love sports. My youngest loves the human body and wants to be a research scientist who cures MS. We buy her anatomy books and skeletons of the human body to encourage that interest. Not sure why soccer is seen as so different, by you.
