I don't wanna burst your bubble bro, but, consider it bursted. This forum (and others like it) are full of kids and old men and everyone in between who area already better than you (or me) and have loads more talent - all of whom have approximately zero chance of ever making a career out of snowboarding. Not to mention the thousands of kids (and old men, and everyone in between) at every hill
across the country who don't participate in the blogs, forums, twitters, etc., who are already throwing down seriously, with an equally zero chance of making a career out of snowboarding.
The market will pay maybe something like maybe a couple hundred people out of 7 billion. You got better odds of getting bitten by a shark in Nebraska.
OTOH if you want to be a "snow journalist" that might be one route you could pursue. But it ain't "pro snowboarding". It's "pro journalism" with a snowboarding slant
There's also film, photo, marketing/advertising/promotions/etc., and the myriad other jobs that every major resort and snowsports industry requires to keep the wheels in motion (accounting, finance, HR, etc...). Possibilities are there but you gotta make the right moves at the right time and know the right people and also have a lot of luck.
Not hating, if you wanna shoot for the moon you f*cking go for it I won't stand in your way and hopefully you prove me wrong; but the odds are not in your favor. Good luck!
