I was a young kid who fell in love with snowboarding and I just wanted to snowboard. So I did. I immersed myself in the local industry, I met and rode with kids my own age and anyone that would ride with me. I competed in most events I could. I sent out “sponsor me” CVs. But it was the word of mouth and my riding that got me sponsored.
The industry is a little different these days but I believe it would still take the same principles – ride because you love it. Immerse yourself in the industry as best you can and just shred. The sponsors will come if that is your dream.
