Cutting an onion

It seems that i can never cut an onion right. By the time i get enough of the onion that i need, I'm usually in tears (from frustration and from the onion itself).

Here's a surefire way of doing it right and with minimal tears.

Start by cutting the onion in half from root to tip.
Lop off the top end.
Peel off the outer layer.
Then make several small, vertical slices all the way through the onion.
Next, rotate the onion 90 degrees and slice again, creating a fine dice.
The root end of the onion holds it all together while you slice away.
