tire-biter

A tire-biter is the kind of person who is so focused and tenacious that when they want to achieve something they go after it with such determination they actually succeed; lots of dogs chase cars, but only the successful ones actually get a piece of the tire.

My daughter was a tire-biter when it came to competitive sports; she was determined to score at least once in every lacrosse game she played.
She was such a tire-biter in lacrosse that she averaged two goals per game.
