Go pro or win in semi-pro leagues.

I have been playing COD since Black OPS 1 and want to get into the semi-pro or professional scene. i would like to believe i am a relatively decent player
with over 15,000 + kills and a positive KD. i have a YouTube channel called PhonyName1 i do montages of relatively decent clips on their and have had past tournament experience in Rainbow six siege. I am willing to puut the time and effort in for COD and tournaments in practice and I'm almost always on my computer.
