Lee's lips fell into a pout, a natural look for him. "I was not trying to be careless. I was keeping myself hydrated and taking rest breaks often."

Of course, Lee's idea of a rest break happening "often" was not the same as the average person. One thing he could not agree to, however, was to lessen up his pace. He wasn't the same as the typical shinobi. If he didn't work himself to the bone then he was losing progress rather than gaining anything.
