Get knowledge how mental conditioning works, do mental exercises that will create you a thinking habit, assess you attitude, get rid of mental brakes and fears so that you're not just avoiding mistakes, let your body automated systems work by avoiding overthinking. Don't listen too much about your friends about mental conditioning, as your thinking is personal.
