Well, it wasn't a quote, and it is an old lesson. But still, Luke won by refusing to fight his father.
You must have seen a different movie than I did. He didn't refuse to fight his father, he refused to expediently KILL his father. Even though he did fight his father, even delivering a dismembering blow, he was able to transcend his paralyzing fears of both giving into the dark-side and not protecting the people he cared about. Free from his fear, he became free to simply turn-down Palapatine's command to execute Darth Wheezer. Fortunately, his transcendence unlocked the better part of Anakin's nature, which came flooding out when the emperor brought out his force-Tesla-taze, resulting in the overthrow of the emperor, wheezer, and the armada of lawn darts.
It used to be that having your own quadrotor drone was cutting edge. Now that the average joe can pick one up at their local mall for a couple hundred bucks means that you’ve got to step your game up if you don’t want to be seen as pedestrian. That’s why today’s aspiring UAV enthusiasts are working with swarms. Not just any swarms either, but swarms of nano-quadrotors. These days, budget conscious drone makers are going small to cut costs and shed ounces.
Writing software is more fun than working.
