Has anybody else found themselves getting better skillwise at MW2?

Now this topic would seem pretty obvious as anybody would get better at anything as you put more time in effort into it. But I wanted to make a topic to talk about something lol.

I remember first putting in the MW2 disc, being completely new to Call of Duty, let alone console FPS's all together. You should've seen me, omg it was horrible... like 2-24, 3-17 haahah . But as the days and weeks pass I am often a decent Kill/Death ratio. In the first couple weeks if I came across a head to head enemy, I would always lose. He would always sight in first and I'd go down. Now I win over 50% of those and they drop. Maybe cause I use Sleight of hand pro with Faster ADS but it does help.

One day I'll be as good as Link or the legendary Sopmod. haha.
