gc grind and team tournament grind

I am a keyboard and mouse Champion 2 rocket league player. I am addicted to this game I play a lot and got good within a years' time so I will improve greatly with a good team. I am 18 so I'm not a squeaker, I'm mature, have a good mindset (never get angry keeps team in check), as well I have a 2.3k pc setup so I do not experience any issues while playing. I have the Steel Series Apex Pro TKL as my keyboard and Logitech GPro wireless superlight. Thank you for your time.
