Peace of mind, happy physical state, happy mental state, happy spirit.
I think wellness is fleeting, but can be attained. Its like anything else, practice. Practice makes permanent.
Do the things that make you well. Reduce stress, lose weight, improve relations with people, etc.
For the physical I do Karate and Jiu Jitsu. Obviously that's not everyone's style, but some exercise is a must. Anything that sets your spirit free. Bike, walk, kayak, hack, whatever. As long as its fun, you will most likely keep doing it. That's why I love martial arts. It remains challenging, and is very freeing to my spirit because there is no end. I can continue to improve and learn new stuff for the rest of my life. There are tons of fun activities to do that are good for you, I hope you find one you really enjoy.
My spirit has received some conscientious work lately. My sensei's wife is a chiropractor and acupuncturist. She is excellent with both, and has treated me for some time now. We discuss energy, Rei Ki, acupuncture, and spiritual matters along those lines. Including but not limited to hands on healing, dealing with stress, wellness with the spirit. We have learned a lot from each other. So I get a fix of spirit healing regularly, and its a great help.
(If anyone is reading into this, the sensei knocks your joints and spine and neck out of alignment with ease, and she fixes it with kindness.)
So the martial arts school is the chiro office too, and its turned out to be my wellness center.
I try to relieve stress at work by being chill in traffic (I do repairs on engraving machines, so I drive all day to the shops) and trying to listen to good music. My dog is a big help, and I love him.
I've been trying to keep it chill on the net too. Trying to have some fun little e hang outs that don't stress me out to much. I've been trying to change a few up lately, losing the more stressful, and it has helped.
I still occasionally find myself raging at stuff anyway. When I do I just tell myself to chill out.
The whole practice of being well has worked for me, but I have had to intentionally practice it, it definitely didn't happen on its own.
