Can practice make perfect?

I am wondering about this. I had hockey practice last night. I was awful, embarrassingly so. They did an exercise and I kept running to the wrong place and doing the wrong thing. Of course all the other girls in the team have been playing for ages. They understood the exercise, they ALL got it right and it went like clockwork until my turn. Worst of all I do not play with the team, I just practice with them as the Vets do not practice and I really need help so I dutifully arrive on a Monday and Wednesday evening to provide light entertainment. Honestly, if I was watching me I would dismiss myself as a total airhead. Perhaps I am in over my head but I am not going to leave with my tail between my legs just yet.
