What is the character of an unrestrained person?

Free and easy people are more free and easy, their thoughts are unconstrained, their thoughts are flamboyant and elegant, and their actions are free and easy.

A powerful and unconstrained style means: a powerful and unconstrained style is like flying in the air. Metaphor poetry is unrestrained. It also means that people are impetuous and unrealistic.
