There is no difference between a great mechanic and a great artist.
Any craft can be refined to an art. Any worker can become a skilled artisan. There is a certain kind of mindset, a feeling of zen, that the ultimate mechanic shares with the painter. Any tool can become an extension of the body.
The intelligent mechanic engaged in his job, interested in doing well and finding satisfaction in his handiwork, caring for his materials and tools with genuine affection, is artistically engaged.
