For example, I wouldn't hesitate to sit somebody down if he wasn't performing, even if he was the No. 1 player in the world. I've been sat down before. ↗

I sometimes got distracted easily and allowed my mind to wander when I needed to be focused. It's quite subtle, really, and just being aware of it helps. ↗
