Stop caring about your record, and you will get better.

Seriously, the better sparrers spar in the main room, the only real way to get better is to practice, but its not good practice if youre selective sparring.

Also, if youre sparring consistently, even if youre losing - it will put your name on the map. Better sparrers will notice you and who knows, you'll join a good GST team and go far.
