As per the title, what changes did you make to your training, to your learning, your games, your physical positioning or mental state? Or literally anything else... What was it that you think got you out of low elo to where you are at now?...

For reference I’m silver 1. I feel like I’m often being killed by someone shooting into my chest before I have time to line up a headshot. Should I just be doing the same and aim for the chest, as it takes less time to get on target?
