So if drawing had value even when it was practised by people with no talent, it was for Ruskin because drawing can teach us to see: to notice properly rather than gaze absentmindedly. In the process of recreating with our own hand what lies before our eyes, we naturally move from a position of observing beauty in a loose way to one where we acquire a deep understanding of its parts.
Couple this with the basic idea of habit forming and applied consistency:
Let no youth have any anxiety about the upshot of his education, whatever the line of it may be. If he keep faithfully busy each hour of the working-day, he may safely leave the final result to itself. He can with perfect certainty count on waking up some fine morning, to find himself one of the competent ones of his generation, in whatever pursuit he may have singled out. Silently, between all the details of his business, the power of judging in all that class of matter will have built itself up within him as a possession that will never pass away. Young people should know this truth in advance. The ignorance of it has probably engendered more discouragement and faint-heartedness in youths embarking on arduous careers than all other causes put together.
