Adopted from the following great insight shared by David Rock from the book Your Brain at Work

Cortisol – Stress related

Dopamine – Addictive chemical stimulated by rewards and is short lived

Serotonin – Leadership hormone

Oxytocin – Love hormone leads to fulfillment

“May your cortisol levels stay low, your dopamine levels high, your oxytocin run thick and rich, your serotonin build to a lovely plateau, and your ability to watch your brain at work keep you fascinated until your last breath. I wish you well on your journey.”
