I just recently reached my goal of hitting gc before 1k hours, and my current goal is to climb to SSL before 2k. Many of my peers say its impossible, but is it?

My name is KillSwitch, I am 14 years old, and I am a gc1 RL player. I started off as a casual player back in 2017-18, but last year, I have come back to the game and found it to be competitive. I am looking for a team that can provide help, gameplay, and fun. My free times are usually 10-12 AM PST, 2-5 PM PST, and 7-9 PM PST.
