Yes, I do hack my body language, though not in the ways described in the article.<p>Through college, I had a weak posture, submissive body language, and tended to fidget/move around. I often looked goofy.<p>About six months ago, I decided to improve all that. I consciously developed an upright, chest-out posture. I cut down or eliminated unnecessary motions. I keep my hands extended and parallel to the arms, instead of close-fisted and angled inwards. I keep my chin up and my gaze high. I keep my legs outward and, when comfortable, spread apart.<p>By now, it's all become second nature. And it works. Women react much more strongly to me (in a good way). I feel more confident. My body image has greatly improved.<p>As software developers, most of us spend a lot of time seated in chairs and have less than Adonis-like physiques. I highly recommend body language hacking.
