Be careful with this particular bit of advice. It's only true when looking across the interior of the wheel at the part where you're truing. The thing to understand is that the nipple/spoke interface is right-hand threaded but sometime you work with the parts upside down. Get in the habit of thinking about how the nipple would be turning if it were rightside up.
