The aircraft is pointing skywards. The novice pilot pushes the control forward, attempting to level the aeroplane. However, the pilot pushes far too much on the control column. As a result, the plane now pitches towards the ground. The pilot then rushes to pull the control back. The over correction makes the aircraft pitch up violently. Once again, the pilot tries to correct by pushing the control forward again and the aircraft see-saws. Crashes occur. Over-compensation.

In aviation it is known as pilot induced oscillation.

How many of us go to a friend’s house, or a hotel, and declare the shower to be awkward, useless or damn right difficult to operate? In all but a handful of cases it is you that is useless. Why? You over-compensated or failed to wait.

It takes time for the hot water to reach the shower head. It is as simple as that. Make an adjustment and wait. Wait and wait. If not right, do not over-compensate. Make another adjustment if needed, usually a small one. Wait for the hot/cold water to leave the shower, flow through the pipes, and out of the head.

An astute person can set the perfect temperature in about 10 seconds with three of less adjustments. Others that like to blame anything but themselves, either make do with a lukewarm shower or mess around for far too long.
