Pls help

Anyone want to give me some pointers, tips, and something that’ll keep me determined and motivated to keep playing. I really enjoy everything in the game and how it works. From being able to control walk speed/crouch height, all of the amazing sounds, the small things you can do with a weapon, and how the looting system is laid out. I’ve watched gameplay, tips and tricks videos to get a better understanding. I realize the only way to truly get better in stressful situations is by playing A LOT and creating muscle memory for all the controls. But I’d like to hear people’s input and tricks they use to help them. Also especially some input on how to determine what sounds are what and how to pay better attention to sounds. I really want to get better but it’s just so upsetting to kill a couple scavs or players and either get killed shortly after or not know where the extraction points are. By the way I’m very new to the game. I’ve played 5 or so offline matches on customs and 2 actual games on customs. All of the games I’ve never had a successful extraction.
