It's a common thing for me and other siheng to offer constructive criticism to novice or intermediate students. It helps them, it helps us. But one of the more frustrating things about the martial arts is that you're overwhelmed with criticism. Every now and then it's good to just ignore the minor mistakes and offer some constructive compliments.
I resisted the urge to nitpick on mistakes and complimented a friend the other day on his form, and it made his night. I could tell he was very pleased to hear it.
It made me realize, I don't do that enough. He had been practicing hard and it showed, so it wasn't an empty compliment, but I realized I need to make an effort to give credit where it is due. We need to know when we're doing things wrong, but it's just as important, perhaps even more crucial, to know when we're doing things right. I'm not a teacher but that's irrelevant. We're all kung fu brothers and sisters and need to support each other.
