The difference between someone who is driven by his soul and others in the same profession has nothing to do with the quality or trajectory of their work
Rather, it has to do with intent.
An example of this can be found in the Midrash about Enoch, an ancestor of Noah.
The Sages say that he turned into an angel, but during his lifetime in this world, he worked as a shoemaker.
