Asked about athletes who come from the favelas, she said the biggest prodigies in the sport have come from poor communities and that she is an example: when she started she could not pay the monthly fee, her coach sponsored her training, and in exchange she gave it all her time and effort. She said the project's main aim is that people value their opportunities, and that she and Terencio lead by example.
