 I believe the best way to improve it's when it's playful. I've seen so many guys, Joe, I can't say names, but it's crazy how many guys I've seen that left their career in the gyms because they sparred too hard. Every sparring for them it's about winning the round. You cannot improve like this. It needs to be playful. Of course when you're in training camp and your fight is coming up, you need to somehow trying to recreate that environment of discomfort, that stress. But when you're outside of that preparation zone, you need to be playful. That's when you improve, when it's playful, when it's like a game, because you will be more prone to trying new things. By trying new things, you'll adapt. You'll be like, oh, this one works, this one doesn't work, but the one that works, I keep it in my back pocket and it makes you grow.
