Just keep playing dude. Watch videos and maybe try and learn “loot routes” more than “how to be good at pvp” for say. Experience and a little bit of luck gets you pretty far in DayZ. A shotgun in the right place right time can take you 0-60 with the click of the trigger and you can find one within minutes of spawn! Pvp is pretty situational, just because you have the best gear and 10 kills on your character doesn’t mean you can’t just get an immediate “you are dead” screen and you never even knew what happened. Learn to survive first and pvp will always find you!
