According to Wikipedia "authenticity is the degree to which an individual's actions are congruent with their beliefs and desires, despite external pressures."
There are times being true to ourselves can be like a juggling act in the balance of life. Life doesn't always hand us the situations that coincide with our desires. Solutions sometimes mean external pressures that throw the balance out of wack.
Dealing with the imbalance requires leading with your heart. It often means making someone else happy, but it could be that another's happiness is part of the dream.
Compromise can be a tool to remaining authentic to ourselves. I believe that we reap what we sow.
