An example is when you catch a cricket ball your brain is doing the equivalent of solving differential equations, but you do it unconsciously.

Our mate choices are the ultimate form of consumer choice. I can pretty much fit most of our purposeful behaviours under the umbrella of consumption.

My approach is always to redirect their focus from this nebulous concept of confidence to the concrete tasks at hand. These are tasks they have successfully completed numerous times. Whether they feel confident or not is irrelevant; the real key is maintaining focus in the moment.
