Promoting Positive Psychology

I’ll happily own that I endeavor to create games/mechanics which foster positive behaviors in games. Karma systems, advanced/complex social systems, etc., are strewn throughout my work. Recently, a new Basket of Desirables landed in my sphere: the concept of positive psychology in games. How do we foster/encourage/teach and internalize things like:

Optimism
Curiosity
Zest
Growth mindset
Mindfulness
Flow
Forgiveness
Kindness
Empathy
Gratitude
Purpose

in games? Is it doable? Desirable? I think yes to both.
