From my experience most of this characteristics are true and most of the time I do contradict the opinion of others but what's weird I even argue with myself maybe because I see things in a different perspective though I developed my skills in design later in my college years maybe being left handed helped me improved it. In music it's much easier for me to create my own composition rather than do cover songs when I was in a band but I see myself to be more logical minded than emotional. I'm only left handed when writing, when using spoon & fork but pretty much I'm doing everything with my right hand but I guess my dominant right brain hemisphere is the one in control but it's arguing with my left... Hahaha...
