Um... practice? Join a team in high school. Then join a team in college. There are scouts that watch you to see if you are pro material.
You can simply apply to the college and hope to get accepted and make the hockey team. Otherwise to get a hockey scholarship, it is best to play on a Junior A team that has a good record in order to have University Hockey scouts come watch the Junior A games. Most Junior A teams have University scouts watch games, but only stand out players will be approached by the scouts.
You would need to be so good that scouts come to a game that you play and they have to think you are Extremely good.
No but there is a Hockey belt loop.
You have to be really good and have scouts notice you. The best (and most likely) way to get into the NHL draft is to get a scholarship to play for a college hockey team. If you are good, scouts and NHL executives will notice you and draft you. The odds are very unlikely, however.
You should start trying to get college scouts to look at you at around age 16. This is when you will be a prime target for the scouts.
