Zest 

How do you feel each morning when you wake up? Do you feel tired and depleted, or are you full of energy, ready to take on the day? That ability to feel excited and activated, ready to start the day is not the caffeine in your morning Starbucks calling. It’s something deeper. It’s the character strength of zest and enthusiasm.

Zest is defined in the VIA character strengths manual as mental and physical vigor. It’s about approaching life with vitality, not doing things halfway or half-heartedly, and feeling alive.
