ok, I may not be the best one to answer this as I can barely skate I would say the best way to reach your goal, is first and foremost, practice, practice practice, work on the fundamentals, listen to your coaches and mentors. After all that, if you're good enough, you can try to get drafted I imagine, definitely go to school, so hockey scholorship would be great if you can get one, I imagine the OHL teams have walk on tryouts if you don't get drafted through regular channels. Lots of ways I imagine, but first things first, be really good at the basics and most of all, have fun!
