I'm a terrible stalker and now he's going to find out...

For a long time I've admired one of my teachers and wished to be his daughter. Somehow I developed this theory that when I do what he does, I can become like him. So I googled him and found out he is a really good climber and active at our alpine club.
So I started climbing. One year has passed since, and I've really felt in love with climbing and been climbing as well outside practically all summer long.
I wrote my teacher one month ago because I need his help with something project related. And it came out, he knew I've been climbing and he said he's happy for me and he found it great.
I am going to meet him to talk about the project soon and I think he is going to ask me about climbing as well. I would love to talk with him about it.
But what should I tell him if he asks why I started climbing? I admire you, so I googled you and started climbing because I want to be like you?
