It is frustrating to learn a new sport but it is always rewarding if you stick to it and work hard and most importantly have fun! We play volleyball to have fun with our friends and never forget that :)
My advice would be to be open minded and ready for change. Be as coachable as possible.
Listen to what they have to say because they really do want the best for you. Buying into what they are teaching you can only make you better and always be a good teammate by encouraging others and making those around you better.
