Wikipedia defines freedom as the capacity of the conscience to think and act in accordance with a person's free will. The word freedom has Indo-European origins, coming from the root prī, meaning "to love" - "afraid" comes from the same root, using the prefix 'a' to denote contrariety. Freedom - Fear.
Lately I have thought about the concept of freedom, and I like Wikipedia's definition.
Why do we feel more free in nature, outside the city? There's certainly a part that's due to geographical mobility (we can go wherever we want), but there's also a deeper sentiment, one associated to leaving behind society's restrictions and stereotypes.
For me, the big question is if this kind of liberty hides a path to happiness and, if so, how to follow it.
