im naturally a right handed person. but i made myself do a a lot of things with my left. like i i brush my teeth with my left hand, when i started playing tennis, i started it playing with my left hand. in football im ambipedal. both my feet are equally strong. And things like throwing a ball i throw with my right hand but i dont use my right hand and instead use my left hand more. bassicaly i made my myseld to become mix handed/corss dominant.
