This is how [the] sport has contributed to my personality, toughness and discipline. I have a plan, and I work on it. I was going to add [the] before the word sport since I thought was either a typo or a problem translating what she said, but then I thought it made sense without it too , so I left it as is. Just know that that's not a typo on my part.
