Our brains are evidently programmed to the right side..ever notice the entrance to a store goes to the right ? Many tools are also made for right handed people..also scissors for left handed are not readily found. Teaching a young child (lefty) can be hard..Even to proper way to hold a pencil...When my grandson ( who was left-handed) was young, he and I sat in front of a mirror and when I was trying to teach him tying his shoes,he understood immediately. WE used that method till he mastered it. He also is very creative..perhaps this is because he figured out how to live in a " righty" world.
I have known many left-handed and ALL seem to be creative..however I also know some right-handed who have creativity..Creativity is how you perceive it and what you do with it....funny but the " Torah" is read right to left, unlike most books left to right...interesting?
