Being left handed made it easy since we live in a right handed world and most southpaws already use the right hand to do many things however the best way to gain facility with your right hand and it's what I did is practice writing with it, printing that is. Using the off hand for opening doors and the like is nice but won't give you the fine motor control you need for shaving. Writing will do that. it's not easy and you really have to try hard.
