I've recently moved from the phase where you just use your right hand (my dominant hand) and shave the right side of your face. I'm now shaving the left side of my face and according to the video with Lynn Abrams you have to use your left hand (my non-dominant hand). The video says that it's important to use your left hand.

Well, I tried that and my left hand just sucks. I can't get my angle down and it feels so uncomfortable that I get nervous about how I might mess up (I shouldn't be nervous because it's not like I'm gonna slash my throat if I mess up but I'm still nervous). So today I used my right hand on the left side of my face and I had a great shave.

My question is: Is it mandatory for me to learn to use my left hand or can I get great shaves just using my right hand? Thanks.
