I want to be a pro FPS player one day and i trust myself i will one day succeed

I am a 20 year old guy who has been playing FPS games his whole life starting from all the way from Modern Warfare.
Every fps game i have played my K/D is 2.0 or higher and i want to make something out of my skills and not just play casually at home, i want to show everyone that i can really play.
