Your comment reminds me of an old math professor of mine that told an anecdote about some famous mathematician that used to have a very promising student. However, after a while the student left and a colleague to the famous mathematician asked about the student. The mathematician said: "He lacked creativity, so he left mathematics and became a writer."
That “some famous mathematician” was David Hilbert. When he heard that one of his students had dropped out to study poetry, he said, “Good, he did not have enough imagination to become a mathematician.”
