Like everyone else said its just matter of will and wanting to do it. I am not even 5 feet and yes I have had my troubles because of my height but I like being short and never let it get in my way while climbing unless it actually did like on one climb where i am not tall enough to reach a hold need to finish the climb but I still tried to complete that particular climb 2 or 3 more times not all in the same day. Make the best of your height and find a way to use it to your advantage and have fun. :)
