What I can tell them is the way you become an Olympic champion is to start working now. I tell them why it's always worth it to put the time and effort into something you want to be good at.
One funny thing is, though, I wear my watch on my right hand and I'm actually right-handed. People always wonder why - I don't know myself, I've just always done it that way and I like it the way a good watch fits on my right wrist.
