liberty, freedom of action and thought
It is free will, which can freely manifest itself in actions taken and opinions expressed. People who value freedom want to live according to their own beliefs and principles. They do not like limitations and patterns.
Valuing your own freedom often goes hand in hand with respecting the freedom of others. People who value freedom usually make decisions very consciously.
Sometimes too strong a desire for freedom can lead to loneliness and isolation from the rest of society.
