Some become discouraged and stop being creative due to lack of courage and persistence. Children are naturally curious at birth and are often discouraged by parents because it is more trouble for the parents if the children are creative. We don't find significant hereditary factors involved in creativity. Studies of twins show that training and experience makes all the difference in both figural and verbal creativity. That confounds the heredity versus environment or nature versus nurture issue.
Creativity is developed or squelched by environment and learning.
You've mentioned figure and verbal creativity. A great deal. Figural creativity involves visual and spatial thinking. It is not related at all to verbal creativity. This is a common mistake in creativity research.
