Impatience in CoD4

While playing CoD4, the majority of the players that have high KDRs or dominating the scoreboards are always players who rely on speed and quick aiming. This wouldn't bother me as much if it didn't work as much as it does now. Sometimes, I can outplay the crack heads but in other games, when my KDR starts to drop, I can't help but whip out my SMG, sniff a line, then start doing similar tactics. This usually ends up in a high number of deaths, high number of kills, and finger fatigue. In a realistic FPS like CoD4 I think deaths should mean more to oppose play the style previously described. I honestly, try to not die once, as if it were my life I were "playing" with. I support patience. Try it and you might end up with a higher KDR than usual.
