The golden age of counter strike was a marvelous time. RIP 
It's true, though I think it also generated the first waves of aimbots and wallhacks. I won't forget the first time I realized that it was not luck when some jerkwad headshotted me through a wall while I listened contentedly to opera on the radio.
Still, good times.
Even public hacks found through Google bypassed VAC for years, too. However, now though, Valve has really stepped up their game. 9 out of 10 cheats get detected within a month, except for those league-proof triggerbots and whatnot, but even with only those cheats, you can still get outaimed or outsmarted, because of proper crosshair placement, baiting, faking and playing around with nades.
Great videos.
Glad you liked them. Players who aren't fully aware of these advices will without a doubt get a lot better at whatever FPS they're playing, by applying these tips.
Be as aware as you possibly can, every single round, about these habits, and they will eventually become second nature to you, and you won't even think about them anymore.
Just like peeking at the radar or repositioning your mouse in dead time will also become second nature to you, eventually.
