im 20, 1.68 height, has 6 packs, and does martial arts 8 years. there is a girl in the class who is 17 years old and practices just 4 years,a beautiful girl, 1.74 height, and she is way way better then me. my win lose ratio with her is 30-2 for her. we have a tourenment in few days, and i will be against her in the first round (first to get 10 wins goes to next step). should i give up that round and start just from the seconds round? she is a great fighter and i dont really stand a chance vs her..
