I agree...you got it made...check out this quote maybe it will help
"Consider that the string rotates counter-clockwise on all commercial trimmers. Because of this rotation, the operator must move along a wall from right to left to trim properly. Practically speaking, this necessitates that a right-handed operator walk sideways, if not backwards, while circling a building in a clockwise rotation.
A left-handed trimmer operator, however, doesn't face this problem. He or she holds the throttle grip in the left hand and holds the handle in the right hand. When this person trims along a wall (from right to left, clockwise around a building) following the same path of a right-handed operator, he or she can hold the trimmer straight across the waist with arms fully extended. Most importantly, this operator walks straight ahead.
Obviously, if a right-handed operator converts to a left-handed hold, productivity should increase substantially. The operator now can see where he or she is walking and is less fatigued at the end of the day. And if you train new operators to trim left-handed from the beginning, they will never know the difference. (Of course, in certain situations, you still may need to edge right-handed because of obstacles. An example would be when cars block your path along a curb. In these cases, you can simply switch hands and step out onto the lawn and continue edging until past the obstacle.)"
