When I was little I was rather ambidextrous, but my teachers insisted that I chose a dominant hand so I chose my right hand, since it was the popular thing to do. Now, years later, I don't think I've chosen wisely, as everything I do is left-centric. While I catch and bat and play sports and do everything with my right hand as the lead, my writing is atrocious and there's a huge mental block whenever I try to draw anything from mental inspiration. My vision fades as soon as my pencil-wielding right hand puts the lead to paper.
It's very frustrating, and I as a few others believe this to be the root of my lack of confidence when it comes to using a pencil.
So, I started using my left hand, and I've found myself to be a lot more confident in my drawing, even though all my lines are horrible squiggles. Whenever I have inspiration and I use my left hand, the vision of what I want to draw doesn't fade. I can see it clearly. It's almost like tracing what I can see in my mind's eye right onto the paper.
Thing is, since I lack control in my left hand, everything looks horrible. Yet every time I use my right hand it further cements that hand as being dominant, something that undoes whatever progress I make towards making myself left-handed.
Have you any advice on how to build control and motor skills with my left hand? I'm a quick learner, easily adaptable to any given situation, but I'm at a complete loss as to how to make this change permanent, something I feel will help my art tremendously.
