Thanks for a lovely topic. It's one I've devoted a lot of time to this past year as I reentered therapy to get back to a thriving rather than surviving mentality.
Thriving is multi-faceted to me, encomassing physical, emotional, mental and spiritual well being.
Spiritual health to me includes being aware of the forces in the universe: the energy and spirit of other living beings, the interrelatedness of us all, the beauty of the natural world, and the archetypes that symbolize the unique power of our species in this larger existence. Taking time for those things enhances my ability to thrive spiritually. Spending time on the arts and in nature help with this one. I'm also a vegetarian, contribute to causes I believe in (with room for improvement), and am working on being a conservationist, which helps me keep my spiritual balance.
Emotional health means being authentic: conveying my sadness, anger, fear, and joy, especially with those close to me. It means giving myself opportunities to connect with others including my husband and therapist who are my stalwarts right now, but also to make new friendships, have strong work relationships, and opportunities to give and receive, whether that's playing, venting, or puzzling out life's conundrums. Writing a lot, intensive therapy, challenging myself to be honest with my husband, and reaching out to new friends has helped me with this one. Oh, and making time to cry and express any other emotion.
Mental Health for me means doing meaningful work and engaging in inspiring, challenging, fulfilling activities. I'm working on my bachelor's right now so I can change careers and thrive in a field I will grow in and be engaged by, rather than my less fulfilling current job. Going back to college and practicing a different skillset than the one I use at work, as well as giving myself downtime for resting and pleasure has really helped with this one.
Physical health is one I struggle with most, but for me it simply means eating for pleasure and health, not just emotional eating, which I'm prone to do when stressed, bored, upset, tired, etc. And it means dancing more, walking more, stretching more, breathing mindfully more, just... engaging all my senses and making the most of them, being calm and energized and centered. Trying to take very small steps, such as eating more produce or sitting in the backyard with my laptop to work, or walking my dog more have helped a bit with this one.
So, to me, the image of "thriving" is very clear. It's taken a lot of work to get here though.
