A student of arts was performing in front of one of the best painters in the country, according to him, he had finished the painting and I called him to evaluate it.

As he approached, that great painter observed the work with care and concentration for a while. Then, he asked the student for the palette and the brushes. With great skill he gave a few strokes here and there. When that artist returned the paintings to the student, the painting had changed remarkably.

The student was amazed; before his eyes the work had gone from mediocre to sublime and I ask that great man:
How is it possible that with a few touches they have changed the painting so much? and that man with a firm voice said "You must learn that any detail is important, you must always give everything or it will not be enough"
