How do I help my cousin

So my cousin (whos practically my little sister) loves skiing. She's at the age where she's starting to plan for the future. One of her goals she set for herself is to try to get into the Olympics one day. Being the supportive "big brother" I am, I want to help her. With that said any advice.

Sidenote: context is everything so here ya go. We're both good skiers, she's a skate fan, going to state with our HS ski team, really competitive, and has quite a but of determination (when she wants to). If yall got them questions please ask.
