If you can't hold your breath for 36 seconds you are terribly out of shape. Not surprising though considering the subject of video games. I recommended some low impact jogging at least twice a week.

I know your feeling. I never panic in social. My strafe throws off anyone below a 45 in that playlist. Sometimes, I'll throw off a 50. MLG 45+ High is wicked tough. Your looking at legendary on CE except 20 times harder. People running in twos creeps me out. I hate not having anyone to play with. I know the feeling though bro. But social? Really?

Music! and lots of it

Just chill out and make a warm cup of tea

Every time you die, think to yourself what you did wrong, what you could have done to prevent it, what you will do next time in that situation.

Just treat that fourth kill as if it were any other kill. It always helps to save a grenade as well. Most of my overkills or better were due to grenading and one shotting the last guy.
