It helps to know what success looks like

On a plane when the cabin crew perform their emergency demonstration they don't merely read out the information over the tannoy. No. The cabin crew stand where you can see them. They act. You see them pulling an oxygen mask towards themselves. You see them putting it over their heads. If they're good you see them slowly turning their heads side to side so you can see the elastic at the sides of their heads.

One of my entries in the book 97 Things Every Programmer Should Know is called Make the Invisible More Visible. Visibility is an important aspect of practice and learning. It relates to feedback. You evaluate feedback in the context of your intention - of what you are trying to accomplish. You need a clear idea of where you are trying to get to, of what success will look like when you get there.
