Are you retarded? Take the rim in one hand, hub in the other, put a spoke through the left hand flange, thread it into a left hand hole on the rim. Carry on from there, and you'll soon have a built wheel. It really isn't hard. Left hand flange to left hand holes, right hand flange to right hand holes. Tada. If you need to go to the hole to the right of the valve, then do it, just means you'll end up building from the right hand flange first, not the left.
