Aggressive Brook learning when to be patient at the crease
The destructive 26-year-old has become one of the world's most exciting players across all formats with his attacking batting.
But the gung-ho approach has not worked well in Australia, with his unbeaten 78 in the fifth and final Test on Sunday his highest score so far.
Brook, who has blasted 10 Test centuries, said he toned down his natural instincts in Sydney.
"I've just got to be a little bit more patient and take my ones here and there. And thankfully, I did that today," he said after propelling England to 211-3 at stumps on day one.
