On the left is negative, the right is positive.

Words may have positive or negative connotations that depend upon the social, cultural and personal experiences of individuals. For example, the words childish, childlike and youthful have the same denotative but different connotative meanings. Childish and childlike have a negative connotation as they refer to immature behavior of a person. Whereas, youthful implies that a person is lively and energetic.
