Why drafting works
The other day, a speedster on a bike passed me as I rode along the bike path. For the next ten minutes, I rode right behind him, drafting his progress.
Sure, there's an aerodynamic reason that this works--there's less wind resistance when you ride closely.
But the real reason is mental, not based on physics. Drafting works because, right in front of you is proof that you can go faster.
Without knowing it, you do this at work every day. We set our pace based on what competitors or co-workers are doing. One secret to making more of an impact, then, is figuring out who you intend to follow. Don't 'pace yourself,' instead, find someone to unknowningly pace you.
