Just about every kid in the world who has played on the ice has dreamed of being a hockey player and some take it to upper levels of expertise and that's why it's a good idea to practice hockey if you intend on furthering your hockey goals.
Hockey is a sport that requires exceptional skills of balance, aim, strategy, stamina, teamwork, and physics. It's not just a game of sliding around on the ice trying to hit a puck into a net. It is far more than that and is why it is wise to practice hockey if you intend on playing competitively or professionally. Remember, you'll be on razor sharp skates carrying a big stick with a group of other guys trying to stop you. It takes more than luck to make it in hockey, it takes lots of training and that's why it's a good idea to practice hockey instead of doing things haphazardly.
The skill of a hockey player calls upon not only knowing the rules and regulations but the keen eyed sharp reflexes that any team sport requires as well as how much to practice hockey. The ability to know where your teammates and opposing team are at all times and to zero in on the puck so that you don't miss it is case in point to practice hockey.
The puck can travel at over 100 kilometers an hour when struck with the stick and has been known to move so fast that it blurs even before a high speed camera. Thus saying, it requires the spot on observer, the hockey player to anticipate the puck's speed and trajectory in order to provide an effective block, steal, and of course shot at the goal. Only when you practice hockey will you be able to handle all with the required acumen.
So be vigilant for that acceptable hockey school or hockey training camp. The sooner you begin to practice hockey, the faster you'll excel at your skills.
