I have no idea what your reply meant but here are a few examples of "heart" that have nothing to do with niceness let alone sequins, makeup and music interpretation.
Whether a person is kind or cruel has no bearing on whether they play with alot of heart.
One of my favorite hockey players, Bobby Clark was also one of the dirtiest players to ever lace up a pair of skates. But what a magnificent player he was and more famous for his "heart" than anything else.
He refused to quit regardless of the score and although other players were faster, bigger, stronger and had better shots none had Clark's heart.
I still remember when he was playing for Canada against the Russians back in the 70's. The Canadian coach said to his players between periods "Kharlamov is killing us, somebody has to stop him."
Clark took him off the ice and out of the game and series next shift with a two hander across his ankle. His ferocius play throughout the series exasperated the Russian team and led Canada to a comeback victory.
Clark, far from the most talented player on Team Canada was said to have led them with his heart. About the series Clark later said, "losing was not an option and I was willing to die for Canada."
Figure skating and many skating fans don't know the meaning of "heart" as it has been used to describe certain athletes in major sports.
Roy Keane, the "engine" of some great Manchester United teams was one of the meanest , nastiest sob's in the English Premier league. He was the captain and MVP of Manchester but nowhere near their most skillful player.
It was often said that he lead Manchester with his heart and his will to win led and inspired his teammates.
"Nice guys finish last" may not be part of skating lore but it is certainly a well known saying in many major sports.
Then there was Jackie Robinson. He had HEART.
After Branch Rickey told him what was expected of him Jackie asked, "but don't you want a player who will fight back?"
Rickey told him, "I want a player who is strong enough NOT to fight back."
Extraordinary circumstances called for an extraordinary athelete and MAN. That was Jackie Robinson.
Frank Carroll was heavily criticized by skating fans for treating Mirai like a competitive athlete and not a spoiled princess.
All because he challenged her committment and heart. My, my what a rough and crass sport CoP skating has become.
