My friend Susan practises her songs four hours a day in pursuit of gaining a distinction in her graded exam. She's single-minded in her pursuit of her goal. I've never met anyone so ambitious and single-minded. A clarinetist with whom Joe is rehearsing is also very single-minded and dedicated in pursuit of studying a degree course at a conservatory. They both have something common which is the single-minded pursuit of their goals. A friend of mine Peter is planning on starting a TV network. He's already fired up and ruthless and dedicated in pursuit of profit. He wants to have one channel dedicated to basketball and another channel dedicated to combat sports. He's devoted to making it the best dedicated sports network in the world.
