I'm a lefty too,currently a financial consultant but previously a systems analyst. I have a lot of co-ordination problems e.g.i cannot control both sides of my body when driving etc -(give me a wide berth chaps changing gear and steering at the same time is virtually impossible for me!) playing instruments such as guitar etc also presents problems as does anything which requires my hands to do different tasks.- - however I am an exhibited artist and poet and at my age I am past worrying about it. I do remember at school being told to write with my right hand and also being punished for being unable to knit.
