Whenever you play a shooting game, you click your mouse just as fast as everyone else. When you have the fastest mouse clicking speed, you will be able to perform better. With your friends, you can play the game more efficiently. My clicking speed was also low earlier, so I used a Click Counter tool and practiced every day. Day by day, I improved my speed and began performing better than my friends. You must practice daily if you want to be better than your friends. If you follow my example, your speed will likely increase as well.
