When you’re biking you have to look out for a thing called “target fixation”:
Target fixation is an attentional phenomenon observed in humans in which an individual becomes so focused on an observed object (be it a target or hazard) that they inadvertently increase their risk of colliding with the object. It is associated with scenarios in which the operator is in control of a high-speed vehicle or other mode of transportation, such as fighter pilots, race-car drivers, paragliders, and motorcyclists. In such cases, the observer may fixate so intently on the target that they steer in the direction of their gaze, which is often the ultimate cause of a collision.
As with biking, so with life. Thoreau said that we find the world we look for, but if he rode a bicycle, he might’ve said, “ where you look is where you go.”
