Geelong midfield coach Matthew Knights credits Constable's hard work during the pre-season for his improvement thus far in 2019.
"There were times during running sessions where he pushed himself to exhaustion, and he'll only get better at that," Knights said.
"Charlie's proud of the way he has started, and we're very proud of him too, but he's also quick to defer to the team. That's just him. There's not much fuss about Charlie."
Constable can also call on an illustrious member of his own family for advice. His mother is a niece of three-time premiership coach Mick Malthouse, who has imparted some words of wisdom at various times.
"He told me to just enjoy all the moments along the way because your career is over very quickly. That really resonates with me, because there have been a couple of special moments already," Constable said.
