My coach says this to us ALL THE TIME! It's so true though. It all comes down to your mental strength and your willpower. How bad do you want it? How much are you willing to sacrifice and practice to reach your goal?
One time this girl tried tripping me up but she failed cos I refused to fall over her damn foot. The thing that annoyed me was that she wouldn't let go of my foot (she had hooked her foot onto my ankle) as I was dribbling away with the ball
