Practise. A lot. Don't noob tube, it doesn't help.
I'm going to assume you have MW2, so in that case, try this custom class out.
I'd suggest using a Scar-H, with a heart beat sensor, a Spaz-12 with red dot sight, Scavenger Pro, Cold Blooded Pro, Commando Pro, a Tactical Insertion, and Stun Grenades.
This is a really good all round class, and I got god knows how many kills with it. I'd suggest trying to just find a class that suits your play style.
Try that class and tell me how it goes.
