In flight, sometimes I notice a condition that I want to change, like an airspeed that's too slow. That can be a dangerous problem. I can try to change that by pitching down while looking at the airspeed indicator, but most likely I'll end up too fast. Then I pitch up to go slower... but then, too slow. I'm noticing a problem and fixing it as best as I can, but it doesn't work how I'd like. I will usually end up at the other extreme of what I want.
We call this "chasing the needles", because the pilot notices a problem but overreacts to it, making an uncomfortable ride. If I instead look outside at my airplane's pitch when I adjust it and then let the plane stabilize at the new speed, I'll fly my airspeed much more precisely.
You've seen an extreme that you want to correct, but if your focus is on not doing that extreme, chances are you'll side with the other extreme. In life, what problems have you tried to correct while looking at the problem, instead of looking at the solution?
