I just thought you might be interested in seeing the inspiring little plaque I have hanging inside on my workshop door.
Here’s the translation with a small change to personalize it:
”Theory is when one knows everything, but nothing comes out right”.
”Experience is when everything comes out right, but no one knows why”.
”In Mike’s shop theory and practice are united. Nothing comes out right and nobody knows why”.
-- Mike, an American living in Norway.
