Height

Hello, my name is Alex! I'm 14, years later I had to write here again, but fortunately the topic is not so scary. I am a volleyball player. If you want to be a good (and useful for the team) player, you have to be tall ... At the moment I am 169-173 cm, I don't have an exact measure because I haven't measured myself ... Many of you would tell me that I am you were tall enough to grow even taller, that not everything is due to height, that everything is up to gene, that everything is built on skills ... I must hear this for the hundredth time ... My parents are not so high. My mother is 165-168 cm and my father 173-174 cm .. I really love this sport, I try, I train, I don't give up, but it just depresses me .. The fact that I'm not tall enough ... Really quite I'm better than my higher sets and generally a lot that are above my height. But I want to try to perfection. It's just that if I'm as tall as my friends (about 180-190 cm) it really makes me pretty good, but I AM NOT! I don't blame my parents for my height, if you've thought about it (although I'll never blame them for anything ...). It's all about a gene, yes, yes ... I understand. I read on the internet a lot of time about "growth hormone", I really got a lot of information. I need to sleep more, I understand that, but I'm traveling and I can't afford it at the moment .. Offer me some vitamins, proteins, whatever (that won't hurt me in general) ... About chemistry I will not mention at all because I want to stay clean (I think there is a difference between protein and chemistry). Offer me foods, diets, ways of training, exercises, everything that would help me .. Also please write to me experienced people (I know you are), I do not want to be pasted here by Wikipedia or something like that. I'm asking for help! If someone thinks that this is an insignificant topic, in my opinion it is not, because I am passionate about sports ... Now, as I help you and answer the topics in the other stories, so do you now :) Please the topic let me be published! I will wait for answers :)!
