Like anything, incorporating acts of kindness if done every single day eventually becomes a habit, and second nature. 

Being kind to others releases dopamine, the feel-good chemical in your body, reducing stress and breaking up your daily routine.

Decide to consicously do one nice thing daily. Open a door for someone, wave someone ahead when you're in traffic, or simply smile at a coworker or fellow commuter. 

What have you done today?  

No matter how educated, talented, rich or cool you believe you are, how you treat people ultimately tells all.

Integrity is EVERYTHING.
