You're trying too hard. Snowboarding should be fun. If you are trying to do it to go pro then you are doing it wrong. Learn to ride, figure out ways to go as often as you can. Move to the mountains when you can. I wouldn't give up other aspirations because you are going to go pro. If you are thinking about college, go. Plenty of schools nearby to mountains where you can get a quality degree and plenty of shred. There are tens of thousands of kids who all want to go pro. Maybe 100 of them will. Even less will have a successful career that makes them real money and allows them to ride when they want.
This. I hear people talk all the time that if you have the drive and work hard enough that you can become a pro rider. I hate to tell you, but those people are full of shit. Your parents and teaches lied to you as a kid. You can't be anything you want to be. Sorry.
Not matter how hard most of us work at it, we'll never be pro snowboarders. Why? Because we lack the talent. Most anyone can become a good rider, but there's a big difference between being a "good rider" and being a pro. A BIG difference.
Go ride and have fun. Focus on having fun and being the best rider that YOU can be. If you're good enough to be a pro, you'll become a pro. If not, you'll still have a blast and won't be stressing because you're not a pro.
Also, keep in mind that there are varying levels of "pros". Hell, most can't even agree on what a "pro snowboarder" is. Is it anyone who is sponsored? Do you have to have a certain number of sponsors? Does it depend on what level of comps you're competing in and how you're doing? Hell if I know. If you're talking about Olympic and X-Games level pros, you're talking about a literally just a handful of guys. Those are the elite of the elite. They are the NFL Pro Bowlers of the snowboarding world. If you're talking about guys who completely live off of their snowboarding winnings and sponsorships, again, you're talking about a small handful. Most "pros" are working landscaping jobs, etc. in the summer to be able to live. Sean White is the only guy out there who is legitimately balling ass rich from pro snowboarding.
