Surf riding is repeditive. That's it's problem. The only thing in the video that wasn't a BF or a BR was a tailstand or 2 by Saki.
That doesn't change the fact that I watched the video 4 times, each time a different week, because I wanted to see it again. Everytime I watched it I enjoyed it and still got chills from some of the biggest tricks.
I don't mean to say this as an insult. I say this as constructive criticism. To quit because a few people gave you a hard time shows a lack of character. For every one person who says something bad, there's at least 50 that thought something good. Yet you still give up because of that one person. If I quit everytime I met someone that gave me a hard time in what I was doing, I'd have quit everything, and be doing everything alone.
No matter where you go, or what you do, if it involves other people, you WILL encounter someone who is a problem. The only solution is to shut them all out and just be by yourselves. That to me, isn't a very good solution.
Stand strong and walk through the few insults. For every one person standing in your way, there's a 1000 behind them waiting for you to get past that person so they can praise you for your work.
Hope you change your mind. I was wanting to watch that video again.
