At the moment of truth, you will not rise to the level of expectation but will fall to the level of training. (paraphrase of Archilochus, ancient Greek poet)
The good worker wants to know what is expected of him or her. What is the end product to look like and how is it to function? Or how will success be determined: the effectiveness of our presentation, the number of sales, etc.? Archilochus reminds us that no matter what is expected, without proper training, we will probably fail no matter what our expectations are.
I discipline my body like an athlete, training it to do what it should. Otherwise, I fear that after preaching to others I myself might be disqualified. (1 Corinthians 9:27)
