How to win a fist fight in highschool?

Have your hands in front of your face, if your right handed then have your left foot in front of your right foot for your stance. Now throw alot of 1's, which are left hand jabs(a jab is a quick punch and bring ur hand back in front of ur face fast) Now if u get a hit with your left hand, come in with ur right hand for a strong blow. Never retreat. Keep your momentum if you get some. Opposed to your natural instinct, you wanna stay close to him. Or just bring a knife.
