In electrical engineering, there is this concept of noise, which is any unwanted signal that interferes with the message. The goal is to make your signal so strong that the noise is cancelled out. It is the basis of communication networks.

It turns out that noise, and the need to reduce it is true in many human activities. Managing the signal to noise ratio well allows us to focus on the right information to make good decisions. Although it is tough at times to distinguish between the signal and the noise, it pays off to invest in noise cancellation.

By focusing on the important few, and ignoring the noisy bunch, we can make the investment of our precious time pay off well.
