The artist doesn’t choose his drawing tool. The drawing tool chooses the artist.
You should not feel like a lesser artist if you were chosen by a humble medium like graphite or charcoal. In the hand of an artist, these can be sublimely expressive.
Nor should you feel like a greater artist if you were chosen by a more esteemed medium like watercolor or oil. Many admire these works, however that does not mean the medium is meant for them.
The medium is more than what is on the drawing surface. It is also what happens in the artist’s physical senses when working with the medium. There is a physical sensation when applying graphite to paper that is different from charcoal that is different from a pen loaded with ink that is different from a brush full of paint and so on. Some feel more “right” than others to the individual artist’s senses.
The closer you are to the drawing tool and medium that has chosen you, the closer you become to seeing the world differently. You may even become the hand and eyes for the drawing medium.
