wow cheers!

My advise is for you to team up with someone with more experience till you get the hang of this game, you need to know where the threats are most likely to come from, where you want to be stealth and places you don't want to be caught out in the open. Once you've been killed/sniped a few times you will know where the good spots are.
 I knew you were going to get tagged on that roof right away, but I figured you were going to get sniped from the fire station or sniper hill.
 Till you find a helpful teammate try getting to a second or third floor of a building in the middle of town, turn up the volume so you can hear people reloading/talking etc... When scanning out the windows avoid to much unnecessary side to side movement, when you got a target in sight wait a bit to see if a teammate is near lots of people split up in town. Always cover the stairs, especially after you start shooting and when you first post up in a building to make sure you were not sighted going in. After you feel good about the stairs first look at other sniping positions, again in case you were sighted going in, then at street level.
 Don't linger to long, shoot and scoot. Sometimes teammates are separated by long distances and people will team with random players to kill snipers/bandits. The longer you stay in one spot the better the chances of being found. Don't expose yourself to quick running to loot a body, if you down someone most teammates will take cover and start scanning for you, stay still, cover the stairs out of sight of the windows.
When scanning or hiding be careful of be in too tight near a corner, sometimes your backpack will stick out of the wall giving you away. Reloading/eating/drinking etc. can be heard from very far away and give you away. I could go on and on, you just need to be patient before you become a hunter/bandit, it will take time. Viewers love watching these videos of DayZ  mainly for the interactivity you get with other people, even if that means you get stabbed in the back sometimes or betray them yourself, it gets old fast watching people just camp. Good luck, I'll sub to watch your progression.

You sound so much like SilentRob. Are you influenced by him or is it just a coincidence?

Uhm excuse me I'm trying to have a private convo here pls don't interrupt rude

How the hell did you manage to beat this game in 7 minutes and 36 seconds?
I'm seriously confused how that is even remotely possible.
Every boss room would have to be right next to the starting room or nearly, and you would have to be so fast, that time would start causing relativistic effects in real life. :)
