My friend John practoses their songs on his clarinet six hours a day in pursuit of gaining a distinction in his graded exam. He's single-minded in his pursuit of his goal. I've never met anyone so ambitious and single-minded before. A cornetist with whom he's rehearsing is also very single-minded and dedicated in pursuit of studying a degree course at a conservatory. They both have something in common which is the single-minded pursuit of their goals. Sarah is planning on starting a television network. She's already fired up and ruthless and dedicated in pursuit of profit. She wants to have one channel dedicated to basketball and another channel dedicated to combat sports. She's devoted to making it the best dedicated sports network in the world.
